Which type of gland loses a portion of the cytoplasm when the product is released? is this cell destroyed or can it be repaired?

During secretion, the apocrine gland loses a portion of the cytoplasm. The cells are not destroyed.

Explanation:

Apocrine gland is a type of exocrine gland. The apocrine glands are present in the breast of the lactating mammals.

The apocrine secretion occurs when the release of secretory materials occurs along with the loss of a part of the cytoplasm.

During the apocrine secretion, the  apocrine cells buds the secretions off through the plasma membrane and loses a part of its cytoplasm in the secretion. During the secretion, the cells are not destroyed.
