stem cell A single cell that can replicate itself or differentiate into many cell types
Totipotent – Stem cells that can become any type of cell
pluripotent – Stem cells that can become almost every type of cell (some exceptions)
multipotent Stem cells that have become part of a class of cells, but can differentiate within that class.
Embryonic Stem Cells (ESCs) controversial Can be kept dividing in the lab indefinitely Pluripotent – Cells that can become any cell type except cells to support the growth of a fetus.
Adult Stem Cells (ASCs) – not controversial Cannot be kept dividing indefinitely – they have a limited period for which they grow. Multipotent – can turn into some different cell types. These are used in the body for repair
Cord Blood-derived Embryonic-like Stem Cells (CBEs) Not controversial Can make any type of blood cell. Cannot be kept dividing in culture indefinitely but can be stored.
Therapeutic cloning – Somatic Cell Nuclear Transfer.
From live and dead (growth “arrested”) In Vitro Fertilization embryos.
In Vitro Fertilization Egg and sperm fuse outside of the uterus and are then implanted in the uterus xtra embryos cud be used to collect embryonic stem cells ^side: ESCs have potential disease curing opportunities Controversy: The abortion issuedoes life start at conception?
In Vitro Fertilization – Arrested Embryos UPSIDE Some IVF embryos die In 2006, researchers were able to start an embryonic stem cell line from a dead embryo Upside: If the embryo is already dead, than the researchers are not aborting the embryo
In Vitro Fertilization – Arrested Embryos DOWNSIDE Downside: The researchers do not know why the embryo died. Did it have a genetic defect? This is potentially problematic.
Planaria a nonparasitic worm
Blastocyst The modified blastula stage of mammalian embryos, consisting of the inner cell mass and a thin trophoblast layer enclosing the blastocoel. Also called blastodermic vesicle.
to calculate magnification ou multiply the magnification of the eyepiece by the multiplication of the lens you're using. So for example, if the eyepiece is 10x, and the lens is 40x, that will create a magnification of 400x.
compound microscope allows for greater magnification
