A hormone that stimulates growth, cell reproduction and regeneration.

As days, weeks, months and years passed, the initial samples continued cell reproduction with no signs of faltering, opening the door to all sorts of previously impossible disease testing.

They induce keratinocyte differentiation and reduce epidermal hyperplasia, leading to the slowing of cell reproduction.

Many microbiologists use biotechnology to advance the understanding of cell reproduction and human disease.

In cancer, the mechanisms that control genes and chromosomes in the nucleus break down, and irregular nuclei and pleomorphic changes are signs of abnormal cell reproduction.
