摘要:
The authors studied the embryonic development of the pineal gland of the chicken with the electron microscope. The denomination of ‘pinealoblasts’ was given to the undifferentiated cells which form the primitive pineal outline. In the wall of the pineal cavities, the follicular and parafollicular zones were distinguished; these are formed by type A and type B pinealocytes, the B type being much more abundant. The degenerated cells are constant in the pineal throughout its embryonic development, but much more abundant in the early pha
