Types of [3H]-labeled cells at different survivals
| Survival time (hr) | Birds (n) | Total cells | A cells | B cells | Mitosis | Picnotic | Contact |

Survivals, number of birds, and type of [3H]-labeled cells studied at the four indicated survivals after a single injection of [3H]-thymidine. The number of these cells exposed to the ventricle (contact) and numbers of [3H]-thymidine-labeled mitotic cells are also indicated.
