Since then, a race has been under way to translate this work into human models, and several teams have been able to replicate the very earliest stages of development. Previously, Żernicka-Goetz’s team and a rival group at the Weizmann Institute in Israel showed that stem cells from mice could be encouraged to self-assemble into early embryo-like structures with an intestinal tract, the beginnings of a brain and a beating heart. Robin Lovell-Badge, the head of stem cell biology and developmental genetics at the Francis Crick Institute in London, said: “The idea is that if you really model normal human embryonic development using stem cells, you can gain an awful lot of information about how we begin development, what can go wrong, without having to use early embryos for research.” They then pick up the course of development much further along by looking at pregnancy scans and embryos donated for research. The motivation for the work is for scientists to understand the “black box” period of development that is so called because scientists are only allowed to cultivate embryos in the lab up to a legal limit of 14 days. It would be illegal to implant them into a patient’s womb, and it is not yet clear whether these structures have the potential to continue maturing beyond the earliest stages of development. There is no near-term prospect of the synthetic embryos being used clinically. “We can create human embryo-like models by the reprogramming of cells,” she told the meeting. Prof Magdalena Żernicka-Goetz, of the University of Cambridge and the California Institute of Technology, described the work in a plenary address on Wednesday at the International Society for Stem Cell Research’s annual meeting in Boston. The structures do not have a beating heart or the beginnings of a brain, but include cells that would typically go on to form the placenta, yolk sac and the embryo itself. Thanks in advance for any help.However, the work also raises serious ethical and legal issues as the lab-grown entities fall outside current legislation in the UK and most other countries. I'll add some pics of the garage later when I get the chance. I potentially have many more questions, but this should do for now. If the gap between the chamber and the outer wall is too small to reach, that could lead to contamination of the incubating buckets. I could just roughly split it in half, souns good enough? Also, what about the gap between the wall? My guess is that I should leave it big enough so that I could clean everything. What would be the best way of making the division? In other words, how would I shape the grow room in relation to the incubation area? From what I've read, I should aim for a 1:1 ratio. Also, I plan to fill all the holes and isolate everything. I plan to grow in buckets and stack them and make the greenhouse frame out of wood. My idea was to split it in two and make one half a greenhouse for fruiting, and use the rest for incubation. The first question I have is: is it a good idea to use the same object for incubation and grow room? I'll try updating this thread as I progress so that everyone interested can learn the process along with me. I've spent a lot of time researching and now I have lots and lots of questions. I plan to convert an old garage into my first grow and incubation room and start from there. Hello, I am interested in starting a small-scale oyster mushroom production as a first source of income on my farm that I inhereted.
