Stroma (animal tissue)

In animal tissue, stroma (from Greek στρῶμα, meaning “bed, bed covering”) refers to the connective, supportive framework of a biological cell, tissue, or organ.

The stroma in animal tissue is contrasted with the parenchyma.

Examples include:
 * Stroma of iris
 * stroma of cornea
 * Stroma of ovary
 * stroma of thyroid gland
 * stroma of thymus
 * Stroma of bone marrow

Stromal cells are the non-tumor cells in tumors.
