Eye created from Stem Cells

Scientists in Japan have conducted a landmark study in which they created a basic eye from stem cells. They are the first scientists to make such significant progress in turning embryonic stem cells into a structure as intricate as the eye. In the Journal Nature publication the team describes how they grew an “optic cup” using embryonic stem cells from mice. This form produces the retina and holds the light-sensitive cells necessary to see.

Such a study gives new hope to scientists and researchers who are concerned with investigating diseases that cause blindness and finding treatments for them.  There is also a possibility of one day transplanting retina cells into patients with conditions affecting their vision. The Guardian Website quoted Yoshi Sasai, who led the research at the RIKEN Centre for Developmental Biology in Kobe, Japan: “We hope that such transplantation may recover vision, at least to some partial extent, in patients who lost their eyesight.” He also told the Guardian that the procedure could be repeated with human cells within two years.

Using embryonic stem cells does pose a moral dilemma for many though as the cells from either animal or human embryos are used. However, at Angeles Health International in Mexico there is no ethical problem as all cells are extracted from the patient’s bone marrow and fat tissue. This means there is minimal to no chance of rejection as the cells come from your own body.  Angeles Hospitals treat a range of conditions using adult stem cell application, including heart conditions, diabetes and cancer.
