(2) a layer precipitate A is removed, is by volume 1:2-5 is added PBS and slightly washs, and carries out 200g centrifugations, and centrifugation time is 10 minutes, two parts, upper solution B and lower sediment B are divided into after centrifugation.
(3) a layer precipitate B is removed, is by volume 1:5-10 is added erythrocyte cracked liquid and is placed in horizontal shaker, shakes 20 points Clock carries out 2000g centrifugations later, and centrifugation time is 10 minutes, and two parts, upper solution C and lower sediment C are divided into after centrifugation, Upper solution C is discarded.
(4) a layer precipitate C is removed, is by volume 1:5-10 be added PBS acutely shake, jitter time be 2 minutes, it is laggard Row 200g centrifugations, centrifugation time is 10 minutes, two parts, upper solution D and lower sediment D is divided into after centrifugation, lower sediment D is abandoned Fall.
(5) upper solution A, upper solution B, upper solution D are taken respectively, carries out 5000g centrifugations, and centrifugation time is 10 points Clock after centrifugation, collects all precipitations.
(6) culture medium (the mixing serum of umbilical cord blood for containing 20%) that the precipitation being collected into is placed in MEM is cultivated, and is cultivated Condition is 37 DEG C, and in 5%CO2 incubators, it is primary that culture medium was replaced per 2-3 days.
(7) culture medium by culture 10 days is collected, and 5000g centrifugations is carried out, to be enriched with Cord blood regenerated particle (regenerated particle Form is shown in Fig. 1).
Embodiment 2
The cerebral hemisphere that regenerated particle moves into damage is in belt pattern
The regenerated particle (GFP labels) that experimental group is obtained by tail vein injection embodiment 1 is small to ischemic brain damage Mouse, control group injecting normal saline.
When 7 days, the sliced section of control group brain is all GFP negative (Fig. 2A), but in GFP antibody responses portion Divide positive (Fig. 2 B) in GFP.When 4 weeks, the continuous part of control group part brain is all GFP negative (Fig. 2 C), still It is positive (Fig. 2 D) in GFP in GFP antibody responses part.When 7 days, entire brain part shows almost all of left hemisphere group Knit be ischemic and damage, and be enhance and it is widened.The substance of the GFP positives is in belt pattern (shown in Fig. 2 B arrows) Arrangement is centered around half brain ball of damage.
Embodiment 3
Regenerated particle forms particulate cellular
The regenerated particle (GFP labels) that experimental group is obtained by tail vein injection embodiment 1 is small to ischemic brain damage Mouse, control group injecting normal saline.
Regenerated particle migrates into after brain tissue, they are to be fused into a seedless cell spline structure first, later Further form karyocyte.High power microexamination further confirms the regenerated particle for coming from capillary (see the width of Fig. 4 Shown in arrow) it is first merged before forming granular cell, and further development forms new particulate cellular.
Embodiment 4
Regenerated particle forms dendron shape neuron
The regenerated particle (GFP labels) that experimental group is obtained by tail vein injection embodiment 1 is small to ischemic brain damage Mouse, control group injecting normal saline.
In the brain of ischemic injuries, the regenerated particle of dispersion is connected with each other fusion and forms fiber-like structures, and further shape The neuron expressed at dendron shape.5 days brain parts, one group of regenerated particle was dispersed in a circular region (see figure 5A).A other regenerated particle may be determined clearly.However, 8 days brain parts, most regenerated particles linked each other In dendron shape spline structure in a circular region, at the same time sub-fraction is still in the pattern of dispersion (see Fig. 5 B).2 weeks it Afterwards, we have confirmed that there is the big eucaryotic cell structure or preceding neuronal cell coexpression GFP and nestin of core (see Fig. 6).
Embodiment 5
Regenerated particle participates in updating big abr cell
Regenerated particle can be connected to each other to form long fiber-like structures to generate new cell.It is observed that one The original cilium spline structure of the length of GFP and nestin coexpressions is discharging weak DAPI (see Fig. 7) and is dyeing small cell two It holds (in DAPI shown in arrow), this shows that long cilium spline structure may update new cell.
In order to further confirm that the cell of these nestin expression is stem cell, we are had checked using Laser Scanning Confocal Microscope In the nestin and Oct4 (see Fig. 8) of 4 weeks brain parts coexpression, those nestin common location Zonal expressions are found Oct4, therefore they are stem cells.
Embodiment 6
Regenerated particle is obviously improved cognition and the behavioral function of brain dementia mouse
In the present embodiment, experiment is divided into 3 groups:SAMR1 groups, SAMP8- brine groups, SAMP8- regenerated particle groups. SAMR1 groups do not make any processing, and SAMP8- brine groups give 0.15ml physiological saline tail vein injection processing/moon, and SAMP8- is again Raw particle group gives 0.15ml regenerated particles tail vein injection processing/moon.
Mouse is found in the probability scenarios of underwater platform, at 0 month, SAMP8- brine group and SAMP8- regenerated particle groups Low, indifference between SAMP8- brine group and SAMP8- regenerated particle groups all more notable than SAMR1 groups.At 6 months, SAMP8- salt Water group and SAMP8- regenerated particles group are all significantly lower than SAMR1 groups, and SAMP8- brine group ratio SAMP8- regenerated particle groups are significantly low (see Fig. 9).
Mouse was found in the incubation period of underwater platform, and at 0 month, SAMP8- brine group and SAMP8- regenerated particles group were all It is more significantly high than SAMR1 groups, indifference between SAMP8- brine group and SAMP8- regenerated particle groups.At 6 months, SAMP8- brine Group and SAMP8- regenerated particles group are all more significantly high than SAMR1 groups, SAMP8- brine group ratio SAMP8- regenerated particle groups it is significantly high (see Figure 10).
Two above experiment shows that regenerated particle can obviously improve cognition and the behavioral function of brain dementia mouse.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
