BIOMEMBRANES AND TRANSPORT

Células Estaminais

In this issue, Canal BQ brings together five review articles on membrane biology and approaches to assess membrane structure and function, so that those interested in the field can take advantage of new (and old) methods used in membrane studies. The first two articles (Domingues et al. and Fernandes et al.) start by discussing how atomic force microscopy and FRET can be used to study membrane structure and function. The third article (Conde et al.) reviews fundamental aspects of solute transport across the plant cell membrane. The fourth article (Soveral et al.) summarizes the current knowledge on aquaporin water channels, including the recently disclosed mechanisms of gating of some aquaporin isoforms. The fifth article (Keating et al.) summarizes recent findings concerning the placental transport of folates and the impact that the impairment of this process might exert on foetal growth and development.

Stem cells - what they are, what they are for, and How they are grown in the lab

Células Estaminais

This issue focus on Stem Cells. What they are, what they are for, bioethical problems associated with them and promissing altenatives that may solve them. Several Portuguese scientists have been invited to write five review articles about this theme. The articles Bragança et al. and Correia & Bragança introduce the concept of stem cells. The remaining articles are more specialized, one on neural stem cells (Malva & Bernardino) and two others (Serra et al. e Neves & Ferreira) that discuss novel ways of producing stem cells in the lab. The first three are in Portuguese, but the last two are written in English.
