Smooth Muscle - Development and Stem Cells Embryonic and Postnatal Development of the Smooth Muscle: The vascular smooth muscle cells (SMCs) which populate different vessels arise from several lineages within the developing embryo.t was also shown that at postnatal and adult stages, stem cells from specific niches can contribute to normal and damaged smooth muscle tissue. As such, molecular signatures of the different smooth muscle cell origins are unique and respond rather differently to the same secreted cues.

RIXIMKA DUMARKA Smooth muscle is found within the walls of blood vessels (such smooth muscle specifically being termed vascular smooth muscle) such as in the tunica media layer of large (aorta) and small arteries, arterioles and veins.mooth muscle is fundamentally different from skeletal muscle and cardiac muscle in terms of structure, function, regulation of contraction, and excitation-contraction coupling. Smooth muscle cells known as myocytes, have a fusiform shape and, like striated muscle, can tense and relax.

Vagina Development The embryonic origin of the vagina has been a historically hotly debated issue with several different contributions and origins described. Current molecular studies show the whole vagina epithelium is derived from the paramesonephric (Müllerian) duct with bone morphogenic protein 4 (BMP4) reshaping the intermediate mesoderm-derived Müllerian duct into the vaginal primordium.

Turning Somatic Cells into Pluripotent Stem Cells During embryonic development, specialized cells (e.g., muscle or immune cells) arise from a common stem cell that differentiates via a series of cellular changes triggered by specific gene expression patterns.

- All of these cells are generated from a single, totipotent cell—the zygote, or fertilized egg. Most scientists use the term pluripotent to describe stem cells that can give rise to cells derived from all three embryonic germ layers— mesoderm, endoderm, and ectoderm.These three germ layers are the embryonic source of all cells of the body (see Figure 1.1. Differentiation of Human Tissues).All of the many different kinds of specialized cells that make up the body are derived from one of these germ layers (see Table 1.1.ll of these cells are generated from a single, totipotent cell—the zygote, or fertilized egg. Most scientists use the term pluripotent to describe stem cells that can give rise to cells derived from all three embryonic germ layers— mesoderm, endoderm, and ectoderm.

RIXIMKA DUMARKA Smooth muscle is an involuntary non-striated muscle. It is divided into two subgroups; the single-unit (unitary) and multiunit smooth muscle. Within single-unit cells, the whole bundle or sheet contracts as a syncytium (i.e. a multinucleate mass of cytoplasm that is not separated into cells).mooth muscle cells known as myocytes, have a fusiform shape and, like striated muscle, can tense and relax. However, smooth muscle tissue tends to demonstrate greater elasticity and function within a larger length-tension curve than striated muscle.

- The emerging picture suggests that GnRH cells do not originate from the olfactory placodes, but arise from multiple embryonic origins, and transiently associate with the developing olfactory system as they migrate to ventral forebrain locations.ere, the embryonic origins of GnRH cells are re-examined in light of recent data suggesting that forebrain GnRH cells arise from the anterior pituitary placode and cranial neural crest, from where they migrate to their final destinations.

What does your smooth muscle do? The glomeruli of the kidneys contain a smooth muscle-like cell called the mesangial cell. Smooth muscle is fundamentally different from skeletal muscle and cardiac muscle in terms of structure, function, excitation-contraction coupling, and mechanism of contraction.ating Newest Oldest. Best Answer: Smooth muscle is a type of non-striated muscle, found within the tunica media layer of arteries and veins, the bladder, uterus, male, female, and all animals, gastrointestinal tract, respiratory tract, the ciliary muscle and iris of the eye.

Primitive Streak - Development and Stem Cells The primitive streak originates from the anterior epiblast, and appears as an elongating groove (primitive groove) on the dorsal midsagittal surface of the epiblast, along the anterior-posterior axis of the embryo. The rostro-caudal and medial-lateral axes of the embryo are defined by the primitive streak.The rounded primitive node, or Hensen's node, is situated at the cranial tip of the primitive streak, and contains a depression called the primitive pit.mbryonic Derivatives of the Primitive Streak: Cells from the epiblast migrate into the interior of the embryo via the primitive streak, in a process termed ingression, which involves a cellular epithelial-to-mesenchymal transition (EMT).

- Cardiac muscle is capable of involuntary, strong, rhythmic contractions. C. Smooth muscle-this muscle is not striated and is found in the walls of the visceral organs. Mononucleate cells. In addition to contraction, smooth muscle cells synthesize collagen, elastin, and proteoglycans (like fibroblasts).s a result, neurotransmitters have to diffuse across this connective tissue layer and onto the plasmalemma of the smooth muscle cells in order to initiate the action potential that causes contraction. This is another reason for the slower contraction of smooth muscle cells.

Biological Characteristics of Foam Cell Formation in Smooth Muscle Cells Derived from Bone Marrow Stem Cells Foam cell formation of BMSC-SMC and VSMC induced by ox-LDL. Ox-LDL is involved in the pathogenesis of atherosclerosis. Foam cells, one of the hallmarks of atherosclerotic plaques, develop when monocyte-derived macrophages or smooth muscle cells within the arterial wall take up ox-LDL via scavenger receptors.

2.1 INTRODUCTION The origin of the membrane voltage is the same in nerve cells as in muscle cells. In both cell types, the membrane generates an impulse as a consequence of excitation. This impulse propagates in both cell types in the same manner. What follows is a short introduction to the anatomy and physiology of nerve cells.
