New horizon ovarian transplant and novel vaginoplasty

Title : New horizon ovarian transplant and novel vaginoplasty

Abstract:

Orthotopic vascular ovarian transplant: The world’s first successful ovarian transplant was done in March 2002. Total no of cases twelve done over past 22 years. The indications, technique (video), and the results will be presented.

The novel technique of vaginoplasty resulting into normal vagina: The study shows peritoneal metaplastic conversion to normal vagina by LPV. The progenitor cell responsible for the metaplastic conversion was identified in the peritoneum and different stages of neo?vaginal development. The translational stemness markers NANOG, OCT4, and SOX2 responsible for the neovaginal formation were identified. Their appearance and concentration at different stages of conversion were demonstrated. The neo?vagina has shown upregulation of these translational stemness markers. The study demonstrates the expression of the specific genes (WNT4, WNT5A, and WNT7A) and their role in the formation of the neo?vagina. Furthering this research, manipulating and activating these genes by genetic engineering may lead to the treatment of developmental defects of Mullerian duct and developing the rudimentary uterus to normal size, obviating the need of transplant. To the best of our knowledge, this study is the first to show the metaplastic conversion of peritoneum to normal vagina, identifying the progenitor cell, expression of translational stemness markers, and upregulation of specific genes.

Currently Dr. Mhatre is pursuing the research in developing mesothelial stem cell population for therapeutic applications in Mullerian agenesis.

Biography:

Dr. Pravin Mhatre, Professor Emeritus at G.S. Medical College, KEM Hospital, and N. Wadia Hospital in Mumbai, is internationally recognized for pioneering contributions to reproductive medicine. He led the world's first successful ovarian transplant, an achievement that was declared by BBC World and BBC London on December 24, 2002, as "The significant medical achievement of the year 2002." In 2005, he also established the first ovarian bank. His groundbreaking research includes work on vaginoplasty using progenitor cells and investigations into the genetics of MRKH syndrome. For his exceptional service in family planning, he was awarded the President’s Medal as part of an honorary team. Dr. Mhatre has also been honored with the Civic Gold Medal and Citation by the BrihanMumbai Mahanagarpalika for his contributions to medicine, and was named "Maharashtra-Ratna" in May 2005.
