| This suggests that the c-erb-b2 oncoprotein may possibly be involved in proliferative responses of pancreatic epithelium. |
| The mass was excised and was characterized histologically as another proliferative cystic sebaceous tumor. |
| In other types, such as the blue nevus, proliferative tissue is buried deep within the dermis, the lower layer of the skin. |
| Histologically, these lesions form a spectrum of tumors ranging from benign cystic adenomas to proliferative cystic sebaceous tumors. |
| 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. |
