WebFeb 25, 2016 · Working with mice, Lei and Spradling set out to test their belief that certain undifferentiated germ cells learn to develop into eggs very early during their production in the ovary, when germ cells are found in small clusters of interconnected sister cells, all daughters of the same parent cell. WebCell cycle analysis for both pSGC and feeder cells at the three temperatures revealed that more pSGCs were in the G2/M phase at 31°C than 37°C at the subculture stage. In vitro, pSGCs could stably maintain undifferentiated germ cell and stem cell characteristics for over 60days during culture at 31°C. WebDuring this period, relatively undifferentiated diploid spermatogonia, the immature germ cells, undergo several mitotic divisions to generate a large population of cells called primary spermatocytes. In the second phase the spermatocytes go through the process of two meiotic divisions leading to the formation of haploid germ cells, spermatids. natural wasp repellent plants
