Germ cell tumours Germ cell cancer. Germ cells are the cells in the body that develop into sperm and eggs. They are mainly found in the ovary or testicle. But they can sometimes be left behind in other parts of the body from when you developed in the womb.

Bacteria Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow. Some live in or on other organisms including plants and animals including humans. There are approximately 10 times as many bacterial cells as human cells in the human body. A lot of these bacterial cells are found lining the digestive system. Some bacteria live in the soil or on dead plant matter where they play an important role in the cycling of nutrients.

Human microbiota There is a point of view that human body contains approximately 1014 bacteria cells, while the number of human cells has been calculated to be at least 3.72 * 10 13. The mass of microorganisms are estimated to account for 1-3% total body mass.he human microbiota is the aggregate of microorganisms, a microbiome that resides on the surface and in deep layers of skin (including in mammary glands), in the saliva and oral mucosa, in the conjunctiva, and in the gastrointestinal tracts.

What is the Stratum Germinativum? The stratum germinativum is the deepest layer of the epidermis. It is also referred to as the basal layer of the skin. The epidermis is another name for the outermost layer of skin in humans as well as other mammals. The primary function of this region is to assist in the regeneration of the epidermis.he type of cells provided to the epidermis by the stratum germinativum are known as germinal cells. A germinal cell is simply a cell from which other cells are derived. The germinal cells developed in this layer are kept separate from the dermis by a thin membrane.

- Our bodies are formed from between 50 and 100 trillion cells (a trillion is a thousand billion, or a thousand, thousand million). These cells are organized into tissues, such as skin, muscle, and bone. Each cell contains all of the organism's genetic instructions stored as DNA. However, each cell uses only the instructions from part of the DNA. For example, a muscle cell uses the DNA that specifies the muscle apparatus, whereas a nerve cell uses DNA that specifies the nervous system.

Spam Spam is a brand name for a canned meat product containing ham, pork, salt, flavorings, and preservatives that are mixed and cooked under vacuum pressure. There are other brands of similar canned pork meat products, but Spam—made by Hormel Foods Corporation—is the original and the best-selling of the brands. The standard Spam can is brick-shaped and holds 7 oz (198 g) of meat.

Langerhans cell histiocytosis Langerhans cells, which help regulate the immune system, are normally found throughout the body, especially in the skin, lymph nodes, spleen, lungs, liver, and bone marrow.

Germ Cell Tumors Germ cell tumors are malignant (cancerous) or nonmalignant (benign, noncancerous) tumors that are comprised mostly of germ cells. Germ cells are the cells that develop in the embryo (fetus, or unborn baby) and become the cells that make up the reproductive system in males and females.erm cell tumors are malignant (cancerous) or nonmalignant (benign, noncancerous) tumors that are comprised mostly of germ cells.

cell 1. a type of cell found in the periphery of the islets of Langerhans that secretes glucagon. 2. acidophil (2). alveolar cell pneumonocyte; any cell of the walls of the pulmonary alveoli; often restricted to the cells of the alveolar epithelium (squamous alveolar cells and great alveolar cells) and alveolar phagocytes. cell whose function is to reproduce the organism. Early in development, primordial germ cells are found in the genital ridges of the embryo. Later, in the testis, the primordial germ cells are called spermatogonia, and in the ovary, they are called oogonia.

- Virtually all cells in the human body contain genes, making them potential targets for gene therapy. However, these cells can be divided into two major categories: somatic cells (most cells of the body) or cells of the germline (eggs or sperm).In theory it is possible to transform either somatic cells or germ cells.irtually all cells in the human body contain genes, making them potential targets for gene therapy.

Germ cell Germ cells produce gametes and are the only cells that can undergo meiosis as well as mitosis. These cells are sometimes said to be immortal because they are the link between generations. Somatic cells are all the other cells that form the building blocks of the body and they only divide by mitosis. The lineage of germ cells is called germ line.

Germ Cell Tumors Germ cell tumors are malignant (cancerous) or nonmalignant (benign, noncancerous) tumors that are comprised mostly of germ cells. Germ cells are the cells that develop in the embryo (fetus, or unborn baby) and become the cells that make up the reproductive system in males and females. These germ cells follow a midline path through the body after development and descend into the pelvis as ovarian cells or into the scrotal sac as testicular cells.

Reproductive system The male reproductive system. The main tasks of the male reproductive system are to produce sperm cells and to introduce sperm into the female reproductive tract. Sperm are produced in the testes, the pair of male reproductive glands located in the scrotum, a skin-covered sac that hangs from the groin. Within each testis are hollow tubules called seminiferous tubules where sperm cells are produced.

Germ cell tumor A germ cell tumor (GCT) is a neoplasm derived from germ cells. Germ cell tumors can be cancerous or non-cancerous tumors. Germ cells normally occur inside the gonads (ovary and testis).Germ cell tumors that originate outside the gonads may be birth defects resulting from errors during development of the embryo.ost patients with germ cell cancer will need to be treated with combination chemotherapy for at least 3 cycles.. The chemotherapy regimen most commonly used in germ cell tumors is called PEB (or BEP), and consists of bleomycin, etoposide, a platinum-based antineoplastic (cisplatin).

Human Reproductive System 1 Testes-Male primary reproductive structures that produce male gametes (sperm) and sex hormones. 2  Scrotum-External pouch of skin that contains the testes. 3  Because the scrotum is located outside of the abdomen, it can reach temperatures that are lower than that of internal body structures.

Immature forms are also found in the blood.endritic cells are found in tissue that has contact with the outside environment such as the over the skin (present as Langerhans cells) and in the linings of the nose, lungs, stomach and intestines.

But they can sometimes be left behind in other parts of the body from when you developed in the womb. Germ cell tumours can develop from these cells. They most often develop in the ovary or testicle, as that is where most germ cells are.

Human reproductive system The male reproductive system is a series of organs located outside of the body and around the pelvis region of a male that contribute towards the reproduction process. The primary direct function of the male reproductive system is to provide the male sperm for fertilization of the ovum.

Seeing squiggles. Flashing lights. The eye danger signs you can't afford to ignore 'As the gel pulls away it can tear or detach the retina-the light-sensitive tissue at the back of the eye-cutting off its blood supply so it can no longer send images to the brain.'. Vitreous jelly can get behind the retina and, like wallpaper, the retina can peel off.

The Genetics of Cancer Germline mutations, which are less common, are passed directly from a parent to a child. In these situations, the mutation can be found in every cell of a person’s body, including the reproductive sperm cells in a boy’s body and egg cells in a girl’s body. Because the mutation affects reproductive cells, it passes from generation to generation.

- Germline mutations affect virtually the entire body, and they seem to be present in every cell. A somatic mutation, or one that is caused in the DNA of a single cell sometime during the life, can be caused by an environmental factor or a wrong bonding in the DNA molecule....
