Answer is EPITHELIAL tissue.
Explanation:
Epithelial lining may develop a folding or bulging in embryonic life at certain locations. The tissue fold grows to form a glandular area.
If a connection through duct remains with the original epithelial tissue, then the gland is called exocrine.
In many cases, connection with original epithelial tissue is completely lost and the gland is called endocrine.
Secretion of endocrine gland must be released directly in blood (as an outlet in the form of duct is absent).
Parts of a gland may develop from two different epithelial tissues as in case of pituitary gland.
