| 31. | Unlike BMPs or parathyroid hormone, researchers believe Runx would only affect bone cells and only in small areas.
|
| 32. | The chromatophores had probably been overlooked before, because they resemble ordinary bone cells and are embedded in them.
|
| 33. | He adds that the protein product of the phog gene is thought to regulate other genes in bone cells.
|
| 34. | Bones are constantly being renovated, with cells called osteoclasts breaking down old bone cells, and new cells being built.
|
| 35. | Moustapha Kassem has also studied aging of bone cells and the effects of donor age on their biological functions.
|
| 36. | Jemison was a co-investigator of two bone cell research experiments, one of 43 investigations that were done on STS-47.
|
| 37. | They also need cells that would remain brain cells and not revert to fat cells or bone cells, he added.
|
| 38. | Among other projects, he is working with leg bone cells from rats to fashion replacements for parts of the leg.
|
| 39. | Therefore, it is possible for to manipulate these cells into becoming functional bone cells in new regions of the body.
|
| 40. | Without the downward pull of a gravitational force on these bone cells, they float around randomly and eventually die off.
