ar In biology, regeneration is the process of renewal, restoration, and growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage.[1] Every species is capable of regeneration, from bacteria to humans.[2][3] Regeneration can either be complete[4] where the new tissue is the same as the lost tissue,[4] or incomplete[5] where after the necrotic tissue comes fibrosis.[5] At its most elementary level, regeneration is mediated by the molecular processes of gene regulation.[6][7] Regeneration in biology, however, mainly refers to the morphogenic processes that characterize the phenotypic plasticity of traits allowing multi-cellular organisms to repair and maintain the integrity of their physiological and morphological states. Above the genetic level, regeneration is fundamentally regulated by asexual cellular processes.[8] Regeneration is different from reproduction. For example, hydra perform regeneration but r...

A biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter. Biofuels can be derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes.[1] Renewable biofuels generally involve contemporary carbon fixation, such as those that occur in plants or microalgae through the process of photosynthesis. Other renewable biofuels are made through the use or conversion of biomass (referring to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy-containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas f...

Cell potency is a cell's ability to differentiate into other cell types.[1][2] The more cell types a cell can differentiate into, the greater its potency. Potency is also described as the gene activation potential within a cell which like a continuum begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency and finally unipotency. Potency is taken from the Latin term "potens" which means "having power." Pluripotent, embryonic stem cells originate as inner mass cells within a blastocyst. These stem cells can become any tissue in the body, excluding a placenta. Only the morula's cells are totipotent, able to become all tissues and a placenta. TotipotencyEdit Totipotency is the ability of a single cell to divide and produce all of the differentiated cells in an organism. Spores and zygotes are examples of totipotent cells.[3] In the spectrum of cell potency, totipotency represents the cell wi...

In developmental biology, cellular differentiation is the process where a cell changes from one cell type to another.[2][3] Most commonly this is a less specialized type becoming a more specialized type, such as during cell growth. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. Differentiation continues in adulthood as adult stem cells divide and create fully differentiated daughter cells during tissue repair and during normal cell turnover. Some differentiation occurs in response to antigen exposure. Differentiation dramatically changes a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals. These changes are largely due to highly controlled modifications in gene expression and are the study of epigenetics. With a few exceptions, cellular differentiation almost never involves a change in the DNA sequence itself. Thus, diff...

Human embryogenesis is the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, human development entails growth from a one celled zygote to an adult human being. Fertilisation occurs when the sperm cell successfully enters and fuses with an egg cell (ovum). The genetic material of the sperm and egg then combine to form a single cell called a zygote and the germinal stage of prenatal development commences.[1] Embryogenesis covers the first eight weeks of development and at the beginning of the ninth week the embryo is termed a fetus. Human embryology is the study of this development during the first eight weeks after fertilisation. The normal period of gestation (pregnancy) is nine months or 38 weeks. The germinal stage, refers to the time from fertilization, through the development of the early embryo until implantation is completed in the uterus. The germinal stage takes around 10 days.[2]...

Home › Health › Anatomy › Blood Cells Blood Cells The main cells of the blood are: red blood cells (RBCs) white blood cells (WBCs) platelets Precursor proerythroblasts (pronormoblast, normoblast, or rubriblast) produce erythroglasts. Erythroglasts produce reticulocytes. After about four days of differentiation and hemoglobin production, the erythroglast sheds its nucleus and becomes a reticulocyte. After spending two more days in the bone marrow, the reticulocyte enters the circulation where, twenty-four hours later, they complete their maturation and become indistinguishable from other mature RBCs. An elevated reticulocyte count indicates bleeding. Normal range is from 0-1.5%. Red blood cells (RBCs) (erythrocytes, corpuscles) Mature erythrocytes have no nuclei, and consist mainly of hemoglobin in a supporting framework called stroma. RBC formation takes place in the red bone marrow of the adult and in the liver, spleen, and bone marrow of the fetus. This formati...
