Trophoblast biology: Forum introduction

In mammals, a carefully orchestrated dialogue between the mother and conceptus (embryo/fetus and associate extraembryonic membranes) is initiated during the peri-implantation period of pregnancy as the trophoblast develops, functions to signal pregnancy recognition, and initiates implantation. The purpose of this Forum is to highlight comparative aspects of trophoblast morphogenesis and functio...

Forum on Biogeography : Introduction

many champions. Originally, in pre-evolutionary Europe, biogeography was unified by the common aim of uncovering the centre of origin, a concept derived from biblical texts. Organisms either were created in the places they were found or they moved there from elsewhere (Buffon, 1766; Sclater, 1858). Whether or not the organisms evolved was not an issue in biogeography. Organisms had a centre of ...

Extracellular matrix: Forum introduction

The extracellular matrix (ECM) is now appreciated as a key regulator of cell and tissue behavior [1,2]. Support for this notion has been derived from correlative studies demonstrating large changes in the composition and distribution of extracellular matrix components during tissue development, differentiation and in response to hormone/growth factor/cytokine influences. In addition, a variety ...
