Human embryonic stem cells (hESCs), owing to their potential promise to develop into any somatic cell type, have radicalised biotechnology research and application in clinical medicine. The source of hESCs has traditionally been viable cells retrieved from preimplantation stage embryos grown in culture ...
Stem cell research seeks to further the advancement of the use of stem cells as well as to find an ethical way to study them. In November 1998, researchers found a way to isolate and culture human embryonic stem cells, (Bevington 2005). The ethics of stem cell research has been debated ...
Stem Cells 成人干细胞 • derived from adult tissue 来自成人组织 (hematopoietic 造血组织, mesenchymal 间页细胞组织) • Includes umbilical cord stem cells 包括脐带干细胞 5 Adult Stem Cells • Advantages 优点 - can be isolated from a patient, expanded in culture and given back to the same ...
Though these are the key properties of the hESCs, yet they are not a property of the ICM in vivo and must be a characteristic adopted by the cells during their initial outgrowth in the culture. The use of human embryonic stem cells (hESCs) in cell replacement therapies (CRTs) has been ...

To solve the problem of immune incompatibility, nuclear transplantation has been envisaged as a means to produce cells or tissues for human autologous transplantation. Here we have derived embryonic stem cells by the transfer of human somatic nuclei into rabbit oocytes. The number of blastocysts that...
Embryonic stem cells Embryonic stem cells(ESCs) are pluripotent and typically derived from theinner cell massof the blastocyst-stage embryo. While ESCs are capable of self-renewing indefinitely while retaining their stemness, and generally do not undergo senescence in culture, there are several inhere...
The recent isolation and culture of human embryonic stem cell lines presents new opportunities for reconstructive medicine. However, important problems remain; first, the derivation of human embryonic stem cells from in vitro fertilized blastocysts creates ethical problems, and second, the current ...
