Placenta preservation solution and preparation method thereof

Abstract

The present invention relates to a composition for tissue preservation, and more particularly to a placenta preservation solution and a preparation method thereof. The placenta preservation solution comprises, in 1000 ml of an aqueous solution, 204 mg to 340 mg of potassium dihydrogen phosphate, 1.40 g to 1.50 g of disodium hydrogen phosphate, 7.6 g to 8.2 g of sodium chloride, 149 mg to 261 mg ofpotassium chloride, 100000U-1000000U of penicillin, 60mg-100mg of streptomycin, 12.5g of glucose, 5g of dextran-40, 7.35g of trisodium citrate and 352mg-528mg of vitamin C, and solution pH is 7.33-7.83. The placenta preservation solution is simple in components, stable and safe, has no toxic side effects, and has low cost. The placenta preservation solution is simple in preparation process and can be prepared in a large amount in a short time.

Description

Technical field:

[0001] The invention relates to a composition for tissue preservation, and more specifically, to a placenta preservation liquid and a preparation method thereof. Background technique:

[0002] The human placenta is composed of amniotic membrane, chorionic membrane and decidua basalis. Amniotic membrane and chorionic membrane originate from the fetus, and the decidua in different regions originates from the mother. In addition to playing an important role in fetal development, nutritional support and maintenance of tolerance, the placenta is also a stem cell reserve. Placental tissue is easy to obtain, easy to handle, does not require invasive operations, and its research will not involve ethical and moral issues. Therefore, it has become a research hotspot in finding new sources of human stem cells.

[0003] Because the vitality of the placenta decreases rapidly in a short period of time when the placenta is in vitro, this directly affects the quality of the plac...
