What is the definition of stromal?
Listen to pronunciation. (STROH-mul sel) A type of cell that makes up certain types of connective tissue (supporting tissue that surrounds other tissues and organs).
What are stromal factors?
Stromal cells (in the dermis layer) adjacent to the epidermis (the top layer of the skin) release growth factors that promote cell division. This keeps the epidermis regenerating from the bottom while the top layer of cells on the epidermis are constantly being “sloughed” off the body.
What is the function of stromal cell?
In the bone marrow, stromal cells are generally referred to as non-hematopoietic stem cells. This is because they do not differentiate to produce blood cells. However, they have been shown to regulate the process (hematopoiesis) by regulating hematopoietic stem cells.
Where is the stroma in a plant cell?
the chloroplast
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma.
Are stromal cells stem cells?
Stromal cells – also known as mesenchymal stem cells (MSCs) – are non-hematopoietic, multipotent, self-renewable cells that are capable of trilineage differentiation (mesoderm, ectoderm, and endoderm).
What is the stroma composed of?
The stroma contains fibroblasts, collagen, blood vessels, lymph vessels, nerves, and adipocytes.
What is stroma in chloroplast made of?
The space between the inner membrane and the thylakoid membrane is filled with stroma, a matrix containing dissolved enzymes, starch granules, and copies of the chloroplast genome.
What does stroma look like?
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma.
What are stromal cells in bone marrow?
Abstract: Bone marrow stromal cells (BMSCs) usually refers to a group of multipotential, heterogenous members within the bone marrow that act as stem/progenitor cells of the bone tissue and are indirectly responsible for hematopoiesis.
