The tumor stroma mainly consists of the basement membrane, fibroblasts, extracellular matrix, immune cells, and vasculature. The ovarian stroma is the substance of the ovary—a connective tissue that binds structures together and is enriched with blood vessels, cells, and several hundred thousand follicles. The cancer stroma is important in cancer development, however, whether the aberrant expression of microRNAs (miRNAs) in the cancer stroma is associated with cancer progression remains to be fully elucidated. C) thick fluid enclosed by the inner chloroplast membrane. b. space between the inner and outer membranes of a chloroplast.

Using conditional mice, Chen and colleagues 102 induced SDF-1 disruption on PN7. There is an increasing interest today in cell therapy of the corneal stroma using induced pluripotent stem cells or mesenchymal stem cells since these cells have shown to be capable of producing new collagen within the host stroma and even to improve its transparency.

Stroma definition is - a compact mass of fungal hyphae producing perithecia or pycnidia. In the anterior part, their size is 10-40 μm. Their thicknesses also vary from 0.2 to 2.5 μm. It is made up of all the parts without specific functions of the organ - for example, connective tissue, blood vessels, ducts, etc. Stroma: The supportive framework of an organ (or gland or other structure), usually composed of connective tissue. The stroma is distinct from the parenchyma, which consists of the key functional elements of that organ. The membranes run through a ground substance or stroma. The stroma consists of unstructured connective tissue containing specific elements of an organ, cells capable of reproduction, and fibrous structures that provide support.
