The medical journal Lancet has just announced that doctors have performed the first successful trachea transplant using a trachea crafted from the patient's own stem cells. The New York Times is hailing this as a revolutionary step in regenerative medicine. The surgery took place in Barcelona this past June. Researchers from universities in Spain, Britain and Italy collaborated on the preparation. The patient's original trachea--actually one of her bronchi--had been damaged by severe tuberculosis.

Early Stage Bone Cells Produce Potential Estrogen Substitute,

Cells on their way to forming bone also produce an estrogen-like substance that mimics the naturally occurring female sex hormone estradiol, investigators at the Yale School of Medicine reported Monday in the online edition of the Proceedings of the National Academy of Sciences.

Researchers hope such a molecule might provide some of the benefits but, hopefully, not the health risk of traditional hormonal therapies for menopause and bone loss.

Rapid generation of a functional NK cell compartment

Bone marrow transplants are an important therapeutic tool for treating certain types of cancer as well as genetic diseases affecting the hematopoietic system. Until the transferred stem cells differentiate and reconstitute the immune system, recipients are at increased risk from opportunistic infections. We report the rapid generation of a functional NK compartment in lethally irradiated mice that received bone marrow cells from a syngeneic donor by treatment with IL-2/anti-IL-2 antibody complexes.

"These objective was to assess the differences in bone properties, using quantitative ultrasound (QUS, Sunlight Omnisense™, Sunlight Medical, Ltd., Tel Aviv, Israel), in male athletes involved in a weight-bearing, impact sport (soccer, SC) or a nonimpact sport (swimming and water polo, AQ), compared with nonathletic control (C) males. A total of 266 boys and men, aged 8 - 23 years, were divided into children (11.1 ± 1.0 years; 34 SC, 34 AQ, 25 C), adolescents (14.7 ± 1.2 years; 32 SC, 31 AQ, 31 C), and young adults (19.8 ± 1.1 years; 31 SC, 24 AQ, 24 C) · Training experience varied between 1

Stem Cells May Look Malignant, Not Act It

Whether Bone marrow stem cells enables them to fuel cancer's ability to develop and then spread, as some scientists suspect, is not entirely clear. The findings, available early in this month's online edition of the journal, actually contest the increasingly popular theory that bone marrow stem cells seed cancer. Instead, these cells might simply look like cancer, not act like it.
