ovaries from a young female

A. ovaries from a young female; some oocytes are vitellogenic but all are in early stages. A’. DAPI image of A. B. DAPI image of ovary containing primarily late stage oocytes. C. ovary from an older female containing primarily late stage oocytes. C’. DAPI image of C. (photo Extavour)

parhyale study We follow the fates of isolated individual blastomeres of Parhyale. This is the eight-cell stage endoderm precursor isolated from the rest of the embryo.
