New health with stem cells

(Part I)

Its the latest medical and cosmetic breakthrough that carries the promise of longevity, vitality and beauty. Could this be the proverbial fountain of youth?

In his book Cracking the Stem Cell Code, Christian Drapeau, MSc, sheds light on the science and history behind stem cells.

Beginnings

The discovery of stem cells was gradual. It evolved over a period of time, from 1670 when Antonie van Leeuwenhoek developed the microscope and described cells floating in the bloodstream to Artur Pappenheim, who traced the blood cells location in the bone marrow. But it wasnt until 1909 when Alexander Maximov suggested the actual concept of a stem cell.

The idea was met with skepticism. And it would take more than 50 years before the concept would reemerge, let alone be accepted.

In the 60s, the existence of a stem cell as the precursor of all blood cells was recognized. Then in 1984 came the discovery of CD34, a stem-cell-specific marker which could isolate stem cells from the bloodstream.

Early notable luminaries in the field of stem cells include William Hewson, Franz Neumann, Julius Cohnheim and Paul Ehrlich.

Lifesaver

Near tragedies, present opportunities. In the case of a 1958 nuclear-reactor leak at the Boris Kidrich Institute in Yugoslavia, where six persons were exposed to radiation, stem cells came to the rescue.
