You should be ashamed of yourself. You should hang your head in shame. You have zero honor. You attack other people that you know are correct just because you don't like what they're saying.
Tsuji confirms at least 2 of the 3 problems I cited:
1. He says functionality is still a problem. By functionality he means inductivity and inductivity is one of the big problems I cited. INDUCTIVITY, INDUCTIVITY, INDUCTIVITY.
2. He affirms that many, maybe even all, Androgenetic Alopecia patients will thin in their donor area and when they thin in their donor area newly implanted hair put into their recipient/balding area will also be affected because the cells used to create the newly implanted hairs will come from the donor area. This means that even if Tsuji finds the solution to the inductivity problem the newly implanted hairs will still thin over time the same as the donor area hair thins over time.
These 2 issues (INDUCTIVITY & Androgenetic Alopecia thinning of donor hairs) are 2 of the 3 problem issues I've cited and Team Tsuji confirms that I have a valid point regarding these 2 problems.
Hi Nameless. I already post this following message. I don't know exactly if this is an answer of their issue about the culturing problem but there is an interesting study published this February 2017 from Professor Ken-Ichiro Kamei (Kyoto University)
Title : " Nano-on-micro fibrous extracellular matrices for scalable expansion of human ES/iPS cells" February 2017
Abstract
Human pluripotent stem cells (hPSCs) hold great potential for industrial and clinical applications. Clinical-grade scaffolds and high-quality hPSCs are required for cell expansion as well as easy handling and manipulation of the products. Current hPSC culture methods do not fulfill these requirements because of a lack of proper extracellular matrices (ECMs) and cell culture wares. We developed a layered nano-on-micro fibrous cellular matrix mimicking ECM, named "fiber-on-fiber (FF)" matrix, which enables easy handling and manipulation of cultured cells. While non-woven sheets of cellulose and polyglycolic acid were used as a microfiber layer facilitating mechanical stability, electrospun gelatin nanofibers were crosslinked on the microfiber layer, generating a mesh structure with connected nanofibers facilitating cell adhesion and growth. Our results showed that the FF matrix supports effective hPSC culture with maintenance of their pluripotency and normal chromosomes over two months, as well as effective scaled-up expansion, with fold increases of 54.1 ± 15.6 and 40.4 ± 8.4 in cell number per week for H1 human embryonic stem cells and 253G1 human induced pluripotent stem cells, respectively. This simple approach to mimick the ECM may have important implications after further optimization to generate lineage-specific products.
