Researchers from Japan and France have successfully reconstituted the development of mouse egg cells, known as oocytes, from ...

Scientists Found Cells That Defy the Rules of Reproduction—and Could Change Biology Mitosis is no longer just what you learned in high school. By Elizabeth Rayne Published: May 06, 2025 1:00 PM EDT ...

Based on bioinformatics analysis, the team provided an interested anti-reproductive aging strategy by improving the quality of ovarian stroma cells in the aged ovary. view more Credit: ©Science ...

Most cells in the tissues of most organisms proliferate through somatic cell division (mitosis). This is a continuous cycle where a single cell doubles its genetic information (chromosomes) and ...

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body's typically efficient DNA repair machinery and potentially affecting our health ...

A simple mechanism could underlie the growth and self-replication of protocells - putative ancestors of modern living cells - suggests a study publishing September 3 in Biophysical Journal.

Wani works with a process that uses DNA from “somatic” (or non-reproductive) cells taken from the donor animal being cloned. The nucleus from these donor cells is introduced into an egg and ...

Reproductive cells change throughout development, so a sex definition based on size is tricky. For instance, in developing embryos, the progenitors of eggs and sperm, known as primordial germ ...
