Embryology History

Introduction

These notes are intended to give some historic background to Embryology. Historically, say pre-20th century, Embryology was not easily separated from Medicine, Anatomy and Physiology and other biological sciences. I have also divided, for brevity, into pre-20th century, pre-molecular (lets call it 70's) and the current molecular embryology.

Nobel awards in Medicine

The Nobel Prize Homepage has a searchable database and an annual table of awards.
The Nobel Prize in Physiology or Medicine 2002 - discoveries concerning 'genetic regulation of organ development and programmed cell death' Summary: "The human body consists of hundreds of cell types, all originating from the fertilized egg. During the embryonic and foetal periods, the number of cells increase dramatically. The cells mature and become specialized to form the various tissues and organs of the body. Large numbers of cells are formed also in the adult body. In parallel with this generation of new cells, cell death is a normal process, both in the foetus and adult, to maintain the appropriate number of cells in the tissues. This delicate, controlled elimination of cells is called programmed cell death."
The discovery of Hox genes and other genes related to body pattern formation. The fly Antennapedia mutant during development the embryo incorrectly positions two legs (pedia) where antenna should have been positioned. The discovery of this mutant in opened up the field of developmental genes and this field has recently (1995) been rewarded with a Nobel prize in Medicine.
