Human embryonic stem cells and therapeutic cloning.
The remarkable potential of embryonic stem (ES) cells is their ability to develop into many different cell types. ES cells make it possible to treat patients by transplanting specialized healthy cells derived from them to repair damaged and diseased cells or tissues, known as "stem cell therapy". However, the issue of immunocompatibility is one of considerable significance in ES cell transplant...
متن کاملTransdifferentiation of Human Dental Pulp Stem Cells Into Oligoprogenitor Cells
Introduction: The nerve fibers in central nervous system are surrounded by myelin sheet which is formed by oligodendrocytes. Cell therapy based on oligodendrocytes and their precursors transplantation can hold a promising alternative treatment for myelin sheet repair in demyelinating diseases. Methods: Human Dental Pulp Stem Cells (hDPSCs) are noninvasive, autologous and easy available s...
متن کاملReprogramming by cytosolic extract of human embryonic stem cells improves dopaminergic differentiation potential of human adipose tissue-derived stem cells
The extract of pluripotent stem cells induces dedifferentiation of somatic cells with restricted plasticity. In this study, we used the extract of human embryonic stem cells (hESC) to dedifferentiate adipose tissue-derived stem cells (ADSCs) and examined the impact of this reprogramming event on dopaminergic differentiation of the cells. For this purpose, cytoplasmic extract of ESCs was prepare...
متن کاملCloning, Stem Cells and Ethics
With the arrival of Dolly the sheep, came the first full-blown cloning of an adult mammal, in which the nucleus of an adult cell was transferred to an empty egg cell, jolted with an electric shock to initiate embryonic development, and subsequently implanted in another ewe, to eventually be born as Dolly. The remarkable message of Dolly is that advanced, or differentiated cells, that is cells a...
متن کاملDifferentiation of human embryonic stem cells into neurons
Human embryonic stem (ES) cells are undifferentiated pluripotent cells derived from the inner cell mass of blastocyst stage embryos. These unique cell lines have the potential to form virtually any cell type in the body and can be propagated in vitro indefinitely in an undifferentiated state. These cells are capable of forming embryoid bodies (EB) that contain cells from all three embryonic lin...
