| The polarity and the distinct centre of densely cytoplasmic cells were lost after day 10 owing to the increased proliferative activity of densely cytoplasmic cells. |
| They subsequently determined that cells within the ribbon were dividing, implying that they were part of a region of proliferative stem cells. |
| In mammals, germ cells undergo a small number of proliferative mitotic cell divisions as they migrate to the gonad. |
| This suggests that the c-erb-b2 oncoprotein may possibly be involved in proliferative responses of pancreatic epithelium. |
| In woody plants, the cambial layer in the trunk, branches and roots also retains proliferative capacity. |
| Flies homozygous for such hypomorphic mutations reach adulthood, but often exhibit defects during the proliferative stages of gametogenesis. |
