their own nature. According to Merriam Webster, a teratoma is defined as a tumor derived from more than one embryonic layer and made up of a heterogeneous mixture of tissues, such as epithelium, bone, cartilage, or muscle. The name teratoma, originates from the ancient greek prefix of terato, meaning monster, combined with the suffix oma, meaning mass. Therefore, it can be interpreted, the phrase teratoma, denotes a monstrous mass. Indeed, teratomas, are of grotesque quality, seeing as they are not
Gastrulation is one of the most important phases in the life of multicellular organisms. Blastula, a single layered cell structure converts into trilaminar structure with three layers, known as gastrula. The word ‘gastrula’ means stomach, since stomach (archenteron) is the first thing formed during gastrulation. There are basically three main events that occur during gastrulation. These are as follows; 1. Formation of three primary germ layers. 2. Basic body plan and body axes are established. Three
cause harm. Most people use stem cells to cure fatal illnesses. The one researcher that put stem cells out in the science world so people could understand it better was Leroy Stevens. His first encounter with stem cells was with a mouse that had a teratoma. Most people don’t understand the need for stem cells. There are many reasons why we research stem cells. Stem cells can be collected form a wide variety of places. The studies of stem cells have been around for many years. There were many people
newly pregnant mother to stray away from using prescription or nonprescription drugs. Many women in the U.S. are given prescription drugs during pregnancy that could have a negative effect on the fetus. Prescription drugs that can contribute to teratomas are antidepressants, certain hormones, and antibiotics. Nonprescription drugs can also have a negative effect on the fetus and the mother. Although small doses of aspirin will pose no threat, high doses can contribute
bone and spreads to other parts of the body, while secondary bone cancer starts elsewhere in the body, then spreads to the bone. Many primary bone cancers can only be found on specific bones (Ewing’s sarcoma is located in the shin or thigh bone, teratomas is in the tailbone). One specific primary bone cancer is osteosarcomas. Osteosarcomas is the most common type of bone cancer. This cancer develops mostly in kids and young adults, and can develop on most bones in the body
The Controversy over Stem Cells and Parkinson's Disease Without any thought, without even noticing it happens, when one has an itch, they scratch it. The arm moves up to the face, the fingers reach down and move across the skin. This series of actions, which many of us do everyday is something individuals with Parkinson's disease struggle with every moment of their lives. Simple movements are replaced by frozen limbs that they or their nervous system can not move. Described by many as a type
Cellular Components of Breast Milk General Cellular Components of Breast Milk Breast milk is most commonly known as a source of nutrition for an infant; however it also provides cellular components that help the baby grow and obtain ideal function. Breast milk must contain a variety of cellular components to provide nutrition, immunity, and a variety of other functions. Some of the basic contents of breast milk include proteins, fats, glucose and vitamins to provide nutritional support for the
The Cape Sundew (Drosera capensis) Introduction: The Drosera capensis, or more commonly known as the cape sundew is one of the most unusual and spectacular plants found in our world. This eudicodic angiosperm is a small-rosette forming, carnivorous species, meaning that it eats insects or anything else small and unlucky enough to land on it. The cape sundew is one of the most common sundews in cultivation due to its small size, durability and gratuitous amounts of seed production, making it a frequent
Organogenesis takes its roots from two Greek words: organon, an instrument, tool, or organ, and genesis, a beginning or creation. With this in mind, one can intuitively infer the basic meaning of the word organogenesis; that is, the creation of an organ. What it means in context to medicine, however, may not be so easily predicted. If any man (or woman, for that matter) of medicine fifteen years ago was asked about the meaning of organogenesis, he or she may tell you that it is the development of
Induced pluripotent stem cells (iPSCs) have the capacity to have a widespread impact on biomedical research and therapeutic approaches to an array of diseases and disorders. These stem cells are of extreme potency because they can self-renew in culture while maintaining the capability to become virtually any cell type (Zhu and Huangfu, 2013). While there are many ethical concerns regarding embryonic stem cells, induced pluripotent stem cells arise from adult somatic cells that can be reprogrammed
