非洲爪蟾卵母细胞在许多基础生物学研究中被广泛使用。卵母细胞的主要限制之一是它们的储存寿命短,大多数去卵泡卵母细胞在10天或更短的时间内物理退化。在此,我们确定了一种基于3D cultrex的存储介质,该介质结合了基于细胞外膜的水凝胶来维持卵母细胞的完整性。在这些处理下,与标准条件相比,卵母细胞的寿命增加到20多天。该处理保留了卵母细胞膜的完整性,并且不干扰mRNA或cdna衍生蛋白的表达。
Xenopus laevis oocytes are commonly used in many fundamental biological studies. One of the major limitations of X. laevis oocytes is their short storage lifespan with most defolliculated oocytes physically deteriorating in 10 days or less. Herein, we identified a 3D Cultrex-based storage media that incorporates extracellular membrane-based hydrogels to maintain oocyte integrity. Under these treatments, the lifespan of the oocytes increased to more than 20 days compared to standard conditions. The treatment preserved the oocytes membrane integrity and did not interfere with mRNA- or cDNA-derived protein expression.
