Definitions
- the present invention relates to a cryopreservation protocol of high viscosity biological samples such as invertebrate sperm samples and more particularly to a novel protocol that allows cryopreservation of very high viscosity sperm samples such as for example crustacean sperm samples , preserving in an integrated way the viability of the cellular package contained in said samples.
- Cryopreservation of tissue samples and biological fluids is one of the most commonly used preservation techniques in biology to keep cells alive and in good condition for prolonged periods of time, without hardly altering their physiognomy or metabolic activity, stop cryopreservation. tissue and / or fluid in a stasis state in which cellular metabolic activities stop completely preventing enzymatic degradation processes from taking place.
- tissue samples and / or biological fluids must undergo a previous treatment that decreases the probability of crystal formation due to such a sharp decrease in temperature, this is achieved by the addition of cryoprotective substances, which prevent the formation of crystals during the process of freezing either by decreasing the amount of intracellular water and / or modifying its behavior by modifying attractive forces between water molecules, for example by breaking hydrogen bonds.
- cryopreservation protocols such as those mentioned in CN Patent 101703039 A, which describes a dilution solution for sperm material of the Charybdis japan crustacean, whose function is to allow tissue homogenization before putting it in contact with the cryoprotective agents to be used for its conservation in liquid nitrogen tanks, this in order for the cell packet to be in direct contact with the solutions used.
- the cryopreservation protocol described dilutes the sample completely and therefore the physical properties of the sample are lost, which is detrimental to the fertilizing power of the sperm.
- DMSO as a cryoprotective agent and its combination with another compound that maintains cell osmotic balance is not described.
- EP 2641966 Al describes a composition for vitrification processes of biological samples, comprising a cryoprotectant compound permeable to the cell membrane and a cryoprotectant compound not permeable to the cell membrane, the content of the cryoprotectant permeable to the cell membrane of the order from 30% to 50% with respect to the total volume of the composition.
- a cryoprotectant compound permeable to the cell membrane permeable to the cell membrane
- a cryoprotectant compound not permeable to the cell membrane the content of the cryoprotectant permeable to the cell membrane of the order from 30% to 50% with respect to the total volume of the composition.
- Patent Application WO 2015057641 Al protects a system for tissue cryopreservation and the method for carrying out the vitrification of biological samples.
- the vitrification solution used contains a permeable cryoprotectant agent (DMSO) and a non-permeable cryoprotectant agent (Trehalose).
- DMSO permeable cryoprotectant agent
- Tehalose non-permeable cryoprotectant agent
- the treated samples must be completely disintegrated and suspended in order to come into contact with the cryoprotective solution, so the original physical properties of the treated sample would be completely lost. None of the cryopreservation protocols available, allows to treat biological samples of high viscosity without the need for their total disintegration. Also, in all cases it is necessary to completely suspend and homogenize the samples so that they come into close contact with the cryoprotectant agent used, so they would not be susceptible to use when the intention is to preserve the original physical properties of the package mobile.
- the present invention aims to provide a novel protocol for the cryopreservation of high viscosity biological samples.
- a further object of the present invention is to provide a protocol for the cryopreservation of high viscosity biological samples that can preserve their cell viability.
- a further objective of the present invention is to provide a protocol for the cryopreservation of high viscosity biological samples, which allows maintaining high cell viability in invertebrate samples.
- Another objective of the present invention is to provide a protocol for the cryopreservation of high viscosity biological samples, which allows the initial physical properties of the originally treated samples to be preserved.
- a further objective of the present invention is to provide a protocol for the cryopreservation of high viscosity biological samples that allows to preserve the fertility of invertebrate sperm such as for example crustacean and insect sperm.
- Figure 1 shows a histological section of the sperm mass before vitrifying (fresh) showing eosinophilic structures possibly of protein origin (black arrows), included among the sperm (round basophilic structures - white arrows).
- Figure 2 shows a histological section of the thawed sperm mass (after vitrification) of treatment B, showing few eosinophilic structures (circuits). These structures are lost in the vitrification process possibly because they are of protein origin and are cold denatured, while the sperm remain intact (black arrows). 200 fold increase
- Figure 3 shows the comparison of a histological section of sperm mass before freezing or fresh sample (a) and a thawed sperm sample from treatment B (b) where intact sperm (arrows) and some eosinophilic structures (in circuits) are observed shown above in figures 1 and 2.
- the present invention provides a novel protocol for the cryopreservation of high viscosity biological samples, which allows to preserve the original physical properties of the treated samples, without loss of the viability of the cell pack.
- the present protocol is especially useful for achieving cryopreservation of sperm samples of invertebrates such as crustaceans and insects and has proven to be especially useful for shrimp sperm samples.
- the protocol of the present invention comprises the steps of: a) placing a sample of high biological material viscosity, loaded in a suitable device, in a tube or cryovial containing an aqueous extender solution preferably consisting of 2,125 g / kg of NaCl, 0.110 g / kg of KC1, 0.052 g / kg of H3B04, 0.019 g / kg of NaOH, 0.484 g / kg of MgS04 «7H20 and 20 ⁇ 1 per 100ml of extender solution of a solution containing 10,000 IU of penicillin, 10 mg of streptomycin and 25 ⁇ g of amphotericin B, for a period of time between 18 to 22 minutes at a temperature from 21 to 25 ° C without the sample coming into contact with the solution or with the tube walls, using a suitable sampling device;
- Defrosting of the sample is carried out by extracting the sample from the liquid nitrogen and immersing it in a water bath at a temperature of 35 ° C to 39 ° C for a period of 4 to 9 minutes, to later remove it from the cryovial and place it for a period of 15 to 25 minutes in an equilibrium solution containing 0.25-0.5 M trehalose.
- the solutions evaluated to cryopreserve the spermatozoa of the white shrimp P. vannamei were trehalose, dimethyl sulfoxide (DMSO) and Polyethylene glycol (PEG).
- the combination and concentration of the previously mentioned vitrifying agents (trehalose, DMSO and PEG) were assigned to the following treatments: A) 6% PEG and 15% DMSO; B) Trehalosa 0.25-0.5 M and DMSO at 10-15%; and C) Trehalosa 0.25-0.5 M and DMSO at 16-20%.
- A) 6% PEG and 15% DMSO B
- C Trehalosa 0.25-0.5 M and DMSO at 16-20%.
- the sperm samples of each spermatophore were placed in a loading device designed specifically for this type of samples and placed vertically within a 2 milliliter cryovial containing 100 ⁇ of extensor solution. In this process, care was taken that the sample did not make contact with the interior walls of the cryovial or with the solution; The sample was stored for 20 minutes at room temperature (23 ° C). Subsequently, the loading device was introduced in the different treatments leaving only two thirds of the sperm sample in contact with the cryoprotective solutions. This step was crucial in the assessment, since introducing more than 2/3 of the sample into the solution caused its detachment from the loading device, and introducing it less did not allow the correct penetration of the cryoprotective agents into the sample.
- cryopreservative solutions were added in two steps: for treatment A in step 1, the sperm sample was immersed in a solution containing half of the total concentration of the cryoprotective agent (3% PEG and 7.5% DMSO) for one minute .
- Step 2 consisted of immersing the sample in the total concentration of the cryoprotectant agent (PEG 6% and DMSO 15%) for 20 seconds;
- step 1 for treatments B and C consisted of submerging the samples in trehalose for 20 minutes and then, in step 2, immersing only 2/3 in the vitrifying solution B (Trehalosa 0.25-0.5 M and 10-15% DMSO ) or C (Trehalosa 0.25-0.5 M and DMSO at 16-20%).
- the loading device containing the sperm sample was quickly introduced into liquid nitrogen and placed in a 2 mL cryovial. Subsequently, the cryovial was stored for 24 hours in a liquid nitrogen tank between -196 ° C and -200 ° C.
- cryovials were extracted from the liquid nitrogen tank and each sample was quickly immersed in a water bath at approximately 37 ° C for 6 seconds. Subsequently, they were placed for 15-25 minutes in the equilibrium solution (0.25-0.5 M trehalose) and stored at room temperature until used in artificial fertilization or viability assessment. Both the fertilization and the light microscope viability evaluation were carried out at Maricultura del Pac ⁇ fico, SA de CV facilities. The viability probes using fluorescent probes and histology were performed at the Aquatic Genetic Resources Subsystem (SUBNARGENA) facilities. located in the CICESE. To carry out the fertilization, the thawed samples were suspended in the extensor solution described in step a) of the protocol of the present invention and its feasibility evaluated. Ten sperm samples per treatment were assigned for artificial insemination of 10 females ready to ovulate. The only treatment that produced nauplii after artificial insemination was treatment B (Trehalosa 0.25-0.5 M and DMSO 10-15%).
- the samples transferred to CICESE seven of them were used to assess their viability. Thawed samples were transferred to a tube containing 1 mL of extender solution to be disintegrated with a tissue homogenizer for 30 seconds. Once the suspension was made, the cells were stained with the Live / Dead sperm staining kit (Life Technologies, Eugene, OR, USA) as follows: 5 ⁇ L of the SYBR 14 dye was added to one milliliter of the suspension of cells (final concentration 100 nM) and were incubated for 10 minutes in the dark at room temperature (23 ° C); subsequently, 5 ⁇ L of the propidium iodide dye (YP, final concentration 12 ⁇ ) was added and allowed to incubate for another 10 minutes in the dark and at room temperature.
- the SYBR 14 dye 5 ⁇ L was added to one milliliter of the suspension of cells (final concentration 100 nM) and were incubated for 10 minutes in the dark at room temperature (23 ° C); subsequently, 5 ⁇ L of the propi
- the sperm samples in the equilibrium solution were homogenized with 1.5 mL of extensor solution.
- An aliquot of 20 i was examined with an increase of 400X after having stained the aliquots with 10% nigrosine and the morphological changes present were evaluated and recorded.
- Those sperms that kept the morphological characteristics intact were considered viable as those with irregular cell bodies or deformed or absent spines were considered not viable.
- 100 sperm were counted, in triplicate, in at least five fields of vision per sheet examined, finding in all cases a percentage of 100% viability.
