Injection of the human germline cells, engineered to stably express GFP, into human ovarian cortical biopsies leads to formation of follicles containing GFP-positive oocytes 1–2 weeks after ...

Those germ cells that enter meiosis become oocytes, the source of future eggs. Consequently, females are born with a finite number of oocytes arrested in the first meiotic prophase. Within the ...

Nonetheless, Slater's conclusion that the poly(A) tails were elongated by polyadenylation in the cytoplasm of the oocytes after fertilization was still valid and intriguing and set further ...

"In the reconstructed oocytes, the mammoth nuclei showed the spindle assembly, histone incorporation, and partial nuclear formation; however, the full activation of nuclei for cleavage was not ...
