Stroma (from Ancient Greek στρῶμα 'layer, bed, bed covering') is the part of a tissue or organ with a structural or connective role. It is made up of all the parts without specific functions of the organ - for example, connective tissue, blood vessels, ducts, etc.

2019年3月28日 · Stroma commonly refers to the fluid filled inner space of chloroplasts surrounding thylakoids and grana. Initially, the stroma was thought to simply provide support for the pigmented thylakoids.

Distinctive populations of stromal cells with different morphologies and functions include (i) fibroblasts, pericytes, and telocytes that are widely distributed throughout various organ systems; (ii) cells with stemness features, such as bone-marrow-derived mesenchymal stem/stromal cells (MSCs) and adipose tissue-derived stem/stromal cells (ASCs...

The cells and tissues that support and give structure to organs, glands, or other tissues in the body. The stroma is mostly made up of connective tissue, blood vessels, lymphatic vessels, and nerves. It provides nutrients to the tissue or organ and removes waste and extra fluid.

Stroma is the fluid filling up the inner space of the chloroplasts which encircle the grana and the thylakoids. In addition to providing support to the pigment thylakoids, the stroma are now known to contain chloroplast DNA, starch and ribosomes along with enzymes needed for Calvin cycle.

STROMA meaning: 1. the tissue that forms the structure of an organ or body part: 2. the soft structure of some…. Learn more.

2022年2月24日 · (1) (cell biology) The spongy, colorless matrix of a cell that functionally supports the cell. (2) (anatomy) The supporting framework of an organ, a gland or other structure, usually composed of connective tissue cells, as distinguished from the parenchyma cells or tissues performing the special function of the organ or bodily part.

2024年12月27日 · The stroma is a term used in biology to describe the cellular component that surrounds and supports the photosynthetic organs in plant cells. Specifically, the stroma is the matrix-like material that fills the intermembrane space within chloroplasts, which are organelles found in plant cells.

The ‘stroma’ comprises ubiquitous structural cells, providing extracellular matrix (ECM) and support functions in every organ. In this review we take ‘stromal cells’ to exclude cells of haematopoietic origin; for example, tissue‐resident macrophages.
