Pursuing Growth Factors For Speedier Wound Healing
Thomas Mustoe | Nov 27, 1988 | 4 min read
The fundamental role of polypeptide growth factors in stimulating the proliferation of cells and in regulating cell growth (both positively and negatively) has been increasingly appreciated in the last several years (see The Scientist, October 31, page 13). The first growth factor to be discovered—nerve growth factor, in 1951—was initially thought to be an isolated phenomenon. But over the last decade, several other growth factors have been characterized. The study of growth factors

The Misunderstood Proteins of Neurodegeneration
Catherine Offord | Aug 1, 2022 | 10+ min read
The normal functions of peptides that aggregate in Alzheimer’s, Parkinson’s, and Huntington’s have been largely overlooked by scientists, but some argue that they are critical for understanding the development of disease.
Controversial Theory Sparking Research On Alzheimer's
Diana Steele | Apr 4, 1993 | 7 min read
While the most popular theory—that the key to the disease is beta-amyloid, the peptide fragment that accumulates in patients' brains—continues to gain ground, some worry that devoting all research to the beta-amyloid theory may be dangerous.

Drug Makers on the Apoptotic Trail
Ted Agres | Jun 24, 2001 | 4 min read
Apoptosis, a key process in the development of embryonic tissue differentiation, later helps to regulate the normal cellular life cycle by destroying damaged cells. When something goes awry, too little apoptosis can make cancer cells resistant to chemotherapy and even death-defiant. At the other extreme, premature or excessive apoptosis has been linked to neurodegenerative diseases, such as Alzheimer's, and to nerve cell loss in strokes. Not surprisingly, many major pharmaceutical companies rec
