Document Summary
Ultimate totipotent stem cell; capability to generate every cell type. During embryogenesis; undergoes symmetric and asymmetric cell division. Hela; first human cell line from cervical carcinoma biopsy of henrietta lacks. Cell contents unequally distributed the organism under strictly controlled. Daughter cells both get genes but inherit different conditions components from mother cell. Multipotent; give rise to some types of cell but not all of them. A cell that has been induced to a state similar to that of a stem cell. Reprogramming of fibroblasts can be accomplished by introducing into differentiated cells three genes that are characteristic of es cells (oct4, sox2, klf4) and one frequently expressed in cancer cells (c-myc) Break cell to cell, and cell to matric interactions. Supplied with proper nutrients; amino acids, minerals, vitamins, salts, glucose, serum etc. Predominant cells in connective tissue, usually divide more rapidly than other cells becoming predominant cell type in culture.
