Description
Technical field
The utility model belongs to Bioexperiment apparatus field, and in particular to a kind of Embryo Culture ware.
Background technology
According to the World Health Organization（WHO）The 10-15% couple at child-bearing age is perplexed by infertility in estimation, developed country.In development
In country（Including China）, the women of child-bearing age for having 1.86 hundred million to 2002 suffer from infertility.The statistics of 2014 shows,
The incidence of China's reproductive population infertility is 12.5%, and infertility number is more than 40,000,000.Vitro fertilization-embryo implanting（in-
vitro fertilization and embryo transfer, IVF-ET）Technology is the important hand of current treatment infertility
Section.From 1978 since the first " test-tube baby " in the world is born in Britain, current developed country helps pregnant birth by IVF-ET
Baby accounted for natus sum 1-3%, estimate whole world test-tube baby births more than 5,000,000 people.
Some IVF-ET deriving technology needs to carry out all embryos of patient individually to distinguish and mark, in order to each
The situation of embryo is analyzed and followed the trail of.For example, implementing preimplantation embryo genetic diagnosis（preimplantation
genetic diagnosis, PGD）, it is necessary to which the embryo all to patient individually cultivate and mark during technology,
Then the cell that biopsy is a small amount of from these embryos carries out genetic analysis, so that it is determined that whether these embryos suffer from heredity disease
Disease, only diagnosing normal embryo can be implanted into patient's body, and abnormal embryo can not be transplanted.Now, for training
The mutually isolated and mark of embryo is then very crucial during supporting, if embryo obscures during culture, having can
Abnormal embryo can be caused to be implanted into patient's body, offspring of the birth with hereditary disease.
Human embryonic in vitro culture is carried out in culture dish, and it is female that laboratories in vitro fertilization most of at present carry out ovum
The in vitro culture of cell and embryo are to use common Tissue Culture Dish（Such as 35mm, 60mm or 100mm Petri dish）.It is micro-
Drop culture is the most frequently used Embryo Culture method, and 10-50 microlitres of culture medium exactly is dropped in into culture dish bottom, is then covered above
Coping stone wax oil, embryo is placed in culture medium droplet and cultivated, human embryos are subglobulars and volume is very small, wherein
About 120-150 microns of human fertilization ovum and cleavage stage embryo diameter, about 200-300 microns of blastaea, each droplet can be put
Put 1-3 embryo.
Carrying out the patient of IVF-ET treatments often has multiple embryos to need to carry out in vitro culture, due to the form of each embryo
It is closer to, it is impossible to directly embryo is marked.If necessary to individually be distinguished for each embryo, the most frequently used side
Method is the droplet for preparing respective numbers according to the quantity of embryo in culture dish, and 1 embryo, Ran Hou are placed in each droplet
Reference numerals on each droplet.Because human embryos are close to spherical, and there is the protection of oolemma, embryo will not also occur
The same adherent fixed growth of ordinary cells, is very easy to be moved in culture medium.In addition, culture medium and paraffin oil are
Liquid, the drift for easily occurring droplet.Therefore, mobile and operation microtitre plate needs action is soft, and strength is slightly larger may also
Cause microdroplet dispersion, embryo's drift may be scattered in other droplets by scattered culture medium droplet, cause embryo mutually to obscure, or
Embryo is floated into paraffin oil meter face causes loss.
In addition, there is the culture dish of some commercializations at present（Such as WOW culture dishes) there can be some apertures single at ware bottom
Each embryo is solely placed, in order to enter line delay to the growth course of each embryo by microcam（timelapse）Into
Picture.But these apertures are all under same culture medium droplet, to be not mutually isolated between embryo, and aperture is shallower
Also smaller, slight rocking this may result in embryo and be floated out from aperture.For each droplet individually culture, more hold
Embryo is easily caused to obscure.
The method insured the most is to prepare a culture dish for each embryo and individually mark and cultivate, but is worked as
When patient's embryo's quantity is more（Such as 10-20 even more more）, then need substantial amounts of culture dish, this will dramatically increase cost,
Operating time and difficulty.
Therefore, how simply, it is safe and reliable to embryo carry out individually isolation cultivate and mark, prevent embryo it
Between mutually obscure, be the problem that most laboratories in vitro fertilization are not yet solved very well.This problem is solved, is implementing PGD etc.
During special IVF-ET deriving technologies, operating efficiency will be significantly improved and medical-risk is reduced.
