New Methods For Increasing Embryonic Stem Cells Supply

By on January 27, 2014

A new method has been developed by an international research team, which helps in the production of high clinical quality embryonic stem cells on large scale without the destruction of human cells.

This new development is going to be a important milestone in the industry of stem cell research.

Karl Tryggvason, Professor of Medical Chemistry at Karolinska Institutet in Sweden and Professor at Duke-NUS Graduate Medical School in Singapore, and Outi Hovatta, a professor at Karolinska Institutet have developed this method.

According to the researchers, it is possible to pick one single cell from embryo, use it, refroze it, and then again place it in the uterus of woman.

Embryonic Stem CellsActually, this process is already in existence, it used in Pre-implantation Genetic Diagnosis (PGD) analyses.

This PGD analysis is actually used for detecting any possible hereditary diseases. In this process, a genetic test is been conducted on a single cell of an in vitro fertilized embryo. If there aren’t mutations found on this cell, then embryo is again placed into the uterus of woman. This embryo develops into a healthy child.

Karl Tryggvason said that embryo, which is actually with eight cells can survive even after one removing one cell from it. After removing this single cell, it is cultivated on human protein, where it duplicates and multiplies without any contamination of cell.

Researcher also said that with this more and more embryonic stem cell without any contamination can be produced. These cells can be developed in any kind of cell, such as heart muscle cells, insulin developing cells, etc. Once developed, these cells can be used in replacing the damaged cells. This raises a new hope in the field of cell therapy.
