Howard Green, the George Higginson Professor of Cell Biology Emeritus at Harvard Medical School (HMS), a pioneer in the science of skin regeneration, died on Oct. 31 at the age of 90 after having served HMS for 35 years.

Green was credited with developing the first therapeutic application of cultured cells, using keratinocytes for the regeneration of epidermis on severely burned patients. The first large-scale, life-saving use of this procedure was demonstrated with cells grown in Green’s laboratory.

Green was appointed head of the Department of Cellular and Molecular Physiology at HMS in 1980 and served in that role until 1993.
