Somatic cell cycle consists of four phases while early embryonic cell cycle alternates between S and M phases without intervening G1 and G2 phases.

In mammals, the rate of somatic growth is rapid in early postnatal life but then slows with age, approaching zero as the animal approaches adult body size. To investigate the underlying changes in ...

In a somatic (body) cell, the cell cycle takes roughly 24 hours to completes, starting with G 1. In G 1 , cells become enlarged, mRNA and new proteins are synthesized, and these are then used ...

Cell cycle speed is key to making aging cells young again Date: January 30, 2014 Source: Yale University Summary: Researchers identified a major obstacle to converting cells back to their youthful ...

Then, the expression level of TERT mRNA and telomerase activity in different period of HeLa cells were compared with human lung fibroblasts (HFL-1) cells (normal cells) and found that somatic ...

A recent study involving murine stem cells showed a recapitulation of the entire female germline life cycle, which resulted in fertilizable mouse oocytes in culture. Among approximately 200 resulta ...
