- The smooth endoplasmic reticulum is suspended in the cytoplasm of many cells and is especially abundant in cells synthesizing steroid hormones (in the adrenal cortex and gonads). It is also abundant in liver cells (hepatocytes), where it is involved in glycogen metabolism and drug detoxification.he mesoderm also gives rise to the vascular system, that is, the heart, arteries, veins, lymph vessels, and all blood and lymph cells. Furthermore, it gives rise to the urogenital system— kidneys, gonads, and their ducts (but not the bladder). Finally, the spleen and suprarenal glands are mesodermal derivatives.

The Cardio Research Web Project At the cellular level, the main components of the postnatal heart are cardiomyocytes, cardiac fibroblasts, endothelial cells and vascular smooth muscle cells (Banerjee I, fusel JW, 2007). In a normal adult heart, cardiomyocytes occupy most of the tissue volume, but they are only 30% of the total number of cells.

- The heart is a muscular pump that delivers blood to the organs, including itself. It is largely composed of specialized muscle fibers called myocytes as well as blood vessels, connective tissues and nerves. In order to coordinate contraction, the nerves and myocytes communicate with an electrical charge.

Bone Marrow & Blood Formation These cells are called pluripotential cells. Other, unipotential stem cells have a limited capacity for self-renewal. Also known as progenitor cells, unipotential cells become committed to forming only one type of blood cell line-erythrocytes (red blood cells), leukocytes (white blood cells), or platelets.arrow looks yellow when it holds many fat cells; it appears red when it has more blood-forming material. The marrow is the principal site for hematopoiesis (blood formation), which, after birth, occurs primarily within the bones of the legs, arms, ribs, sternum (breastbone), and vertebrae (backbones).

- The primary germ layers (endoderm, mesoderm, and ectoderm) are formed and organized in their proper locations during gastrulation. Endoderm, the most internal germ layer, forms the lining of the gut and other internal organs. Ectoderm, the most exterior germ layer, forms skin, brain, the nervous system, and other external tissues. Mesoderm, the the middle germ layer, forms muscle, the skeletal system, and the circulatory system. This fate map diagram of a Xenopus blastula shows cells whose fate is to become ectoderm in blue and green, cells whose fate is to become mesoderm in red, and cells whose fate is to become endoderm in yellow.

Amnion - Development and Stem Cells The somatopleure is formed in both the amnion and chorion, where the ectodermal tissue supplies functioning epithelial cells and the mesoderm generates the essential blood supply to and from this epithelium. The fold tips eventually meet and fuse, forming the amniotic cavity.After fusion, the two layers of the fold become completely separated, where the inner layer forms the amnion, the outer forms the false amnion or serosa. The space between the amnion and the serosa constitutes the extraembryonic coelom.hen first formed, the amnion is in direct contact with the body of the embryo, but about the fourth or fifth week, amnionic (amniotic) fluid (liquor amnii) begins to accumulate within it. As the volume of the fluid increases, the amnion expands and ultimately adheres to the inner surface of the chorion.

The Beat of a Single Cell But it is the complex interaction of numerous cell types that give the heart its ability to pump blood. Some cells form heart connective tissue, other cells grow into heart valves. And muscle cells give the heart its ability to beat and pump blood throughout the body. You can dissolve an embryonic heart into its individual cell types with trypsin, an enzyme that destroys the protein glue between the cells. Plate these cells in a dish and you will see some cells - called myocytes - that beat independently. The cells shown here are from the chick embryo. A single cell beats when a complex series of gates - called ion channels - open and close in an organized manner

Box 1: Cell types of the heart All these cell types contribute to structural, biochemical, mechanical and electrical properties of the functional heart. Atrial and ventricular cardiomyocytes form the muscular walls of the heart (that is, the myocardium). More than 50% of the cells of the heart are cardiac fibroblasts. Endothelial cells form the endocardium, the interior lining of blood vessels and cardiac valves. Smooth muscle cells contribute to the coronary arteries and inflow and outflow vasculature.

Endothelial Cells: Function & Explanation Endothelial cells (Fig.1) line the inside of every blood vessel in the body. They form a one-cell-thick layer called the endothelium, which is also found on the inner walls of the heart chambers and lymphatic vessels (which carry excess blood plasma around the body). The endothelium is very extensive.
