G'day Joanne F,\n\nThank you for your question.\n\nIt is essential if you are studying medicine to have a good understanding of how cells and tissues work. It is also useful to know how particular cells such as blood cells work.\n\nRegards

I'm a biology teacher, and a cell model is a project every year.\n\nUse a HARD beachball about the size of a basketball....or a cheap dimestore basket ball. Cut in in half and use thin wires to suspend the various organelles inside.

Cell division reproduces the same kind of cell.  Cell differentiation is, in embrionic development, the situation wherein cells split-off in different "directions" to become very different things (eg., skin, spleen,...etc.)\n     An editorial:  Stem cell research is investigating the ways that very basics cells (think "undecided") might be introduced and encouraged to grow into cells... organs... to correct some sort of desease or injury.  I think it's a good thing!

Stem cells are cells designated by the body to make copies of themselves to replace tissue. This helps the body regenerate in an orderly maner.\nYou're born with them.

When getting from a baby, they're in the Umbilical Cord:\n\nEmbryonic stem cells (ES cells) are stem cells derived from the inner cell mass of a blastocyst. A blastocyst is an early stage embryo - approximately 4 to 5 days old in humans and consisting of 50-150 cells. ES cells are pluripotent, and give rise during development all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm. In other words, they can develop into each of the more than 200 cell types of the adult body when given sufficient and necessary stimulation for a specific cell type.\n\n:::::\nIn adults, stem cells are found either in blood or bone marrow:\n\nAdult stem cells are undifferentiated cells found throughout the body that divide to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells, they can be found in children, as well as adults. A great deal of adult stem cell research has focused on clarifying their capacity to divide or self-renew indefinitely and their differentiation potential. Many adult stem cells may be better classified as progenitor cells, due to their limited capacity for cellular differentiation.\nNevertheless, specific multipotent or even unipotent adult progenitors may have potential utility in regenerative medicine. The use of adult stem cells in research and therapy is not as controversial as embryonic stem cells, because the production of adult stem cells does not require the destruction of an embryo. In contrast with the embryonic stem cell research, more US government funding has been provided for adult stem cell research. Adult stem cells can be isolated from a tissue sample obtained from an adult. They have mainly been studied in humans and model organisms such as mice and rats.

Stem cells are obtained from Cord Blood.  This is the umbilical cord which connects the infant to his/her mother.  The cells found in this cord are able to differentiate into different types of cells for example, stem cells can grow into a pancreas or a liver, etc. with the stimulus of certain hormones. Stem cell research explores this idea and sees better ways of improving health for example, how can we grow these cells to regenerate nerves for people suffering from spinal cord injuries. It is ongoing but also controversial.

Your body makes cells by the process called mitosis.\n\nHere's a website on mitosis:\nhttp://www.cellsalive.com/mitosis.htm

Cell replacement is accomplished by cell division, which makes more cells to replace cells that have been damaged by wear and tear or senescence (cells growing old and failing to function).\nIn some cases, a single cell of a certain type can divide to give rise to two daughter cells of the same type. This process allows one cell to replace cells of its own type. For example, a liver cell can divide to generate two liver cells. Another example is endothelial cells, which line the inside of our blood vessels; a single endothelial cell will duplicate itself by dividing into two cells.\nIn another case, a special kind of cell, called a stem cell, is used for cell replacement. These cells also divide into two daughter cells. Some of these daughter cells become stem cells that resemble the mother cell. Other daughter cells become the cell type that needs to be replaced. For instance, our skin contains stem cells called basal cells. These basal cells divide into daughter cells. Some of the daughter cells become basal cells that retain the ability to divide, and other daughter cells become specialized into skin cells. That way, some of the cells are used for cell replacement, while other cells retain the ability to divide in the future so that we don't run out of skin cells.\nIn still another case, a single cell called a pluripotent stem cell can divide to generate—and thus replace—lots of different cell types. For example, our bone marrow contains cells called hemopoietic stem cells that can divide to generate the whole range of blood cells. A single hemopoietic stem cell can divide several times to generate red blood cells as well as different kinds of white blood cells.\nThe rates at which cells are replaced vary quite a bit. For example, in the inner lining of the small intestine, cells turn over in a week or less. In the pancreas, the turnover time may be as long as a year or more.\nSometimes the rate of cell division to replace cells depends on the state or size of the tissue. Liver cells rarely divide, but if there is injury to the liver and the liver is somehow reduced, liver cells will divide to get the liver back to the right size. Similarly, in the skin, the basal cells will divide only to keep the skin at a certain thickness. If the outer layers of dead skin peel away more frequently, the basal cells on the inside will divide more frequently to make up for the lost skin. If a person takes good care of his or her skin and there is little damage and fewer cells to replace, the basal cells will reduce the frequency of division.

1)  The cell is the unit of structure, physiology, and organization in living things. \n   2)  The cell retains a dual existence as a distinct entity and a building block in the   construction of organisms. \n   3)  Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).\n\nKeep this as hint and do your homework
