The course will be a short primer to understand how ‘animal cell culture technologies’ have strengthened the bio-medical research from basic research to the modern drug discovery. Animal cell culture was first performed in the very first decade of the 19th century. Since then, tremendous development has taken place in this field. The lectures will help the researcher to appreciate the developments during the last hundred years and will help them to independently set up cell culture laboratories. For non-biologist, it will be an informal way to demystify the intriguing routes of biomedical research where cell culture is a very ‘potent tool’.
