HOUSTON - Illuminating the molecular details of normal sperm development, demonstrating how chemotherapy or radiation can leave a man or boy sterile, and pursuing ways to restore fertility have earned a major honor for a scientist at The University of Texas M. D. Anderson Cancer Center.
Marvin Meistrich, Ph.D., professor in M. D. Anderson's Department of Experimental Radiation Oncology, will be inducted as a fellow of the American Association for the Advancement of Science at the association's annual meeting Saturday, Feb. 14, in Chicago.
"Our goal is to find ways to restore the fertility of the thousands of young men and boys every year who receive treatment that might leave them sterile while curing their disease," Meistrich said.
AAAS, founded in 1848, is the world's largest general scientific society. Meistrich is the eighth AAAS fellow on M. D. Anderson's faculty.
"Addressing quality-of-life issues that arise from surviving cancer is an increasingly important aspect of our research. Recognition of Dr. Meistrich's leadership and innovation in this field is richly deserved," said Raymond DuBois, M.D., Ph.D., M. D. Anderson provost and executive vice president and an AAAS fellow since 2004.
Before undergoing treatment now, men can bank their sperm for later in vitro fertilization. Boys have no options for later reproduction. Chemotherapy and radiation destroy stem cells called spermatagonia that differentiate into sperm. If all the stem cells are destroyed, sterility results.
"An important focus of our research is the possibility of banking these sperm stem cells before treatment and then transplanting them later to launch normal sperm production," Meistrich said. This procedure is done now in mice, and Meistrich's plan is to attempt the same in primates.
Normal sperm production begins with the spermatagonia, which either divide into more stem cells or differentiate into cells called spermato
