	Mention the phrase "diverse ecosystem," and it conjures images of tropical rainforests and endangered coral reefs. It also describes the human colon. A new study reveals in greater detail than ever before the full extent of the bacterial community inhabiting the human bowel -- 10 times more diverse than previous research had suggested.

•	Inhibitory effect of mesenchymal stem cells on lymphocyte proliferation
	We investigated the mechanism underlying the inhibitory effect of rat mesenchymal stem cells (MSCs) on non-specific mitogen-stimulated lymphocytes (LCs) and lymphoblasts (LBs). We used MSCs of passages 2-8 prepared from Sprague-Dawley (SD) rats. LCs were isolated from the spleens of SD rats. Mixed LCs reactions of mitomycin C-treated MSCs with concanavalin A (ConA)-stimulated LCs or LBs were performed, and the proliferation inhibition effect was tested by MTS assay. The cytotoxicity of MSCs against naïve and ConA-stimulated LBs was detected, after co-culturing for 24 h, by lactate dehydrogenase release assay. The rate of apoptosis of ConA-stimulated LBs was measured by flow cytometry after incubation with MSCs for 9 h in the ratio 10:1. The MSCs were treated with Fas ligand (FasL), transforming growth factor (TGF)-[beta], and interleukin (IL)-10 blocking antibodies and co-cultured with ConA-stimulated LBs to observe the apoptosis and growth inhibitory effect. The main outcomes were bone marrow-derived adherent CD29+, CD44+, CD45-, CD54+, CD95+, and SH-2+ MSCs. FasL, TGF-[beta], and IL-10 production by MSCs were visualized by immunocytochemical analysis. MSCs exhibited a dose-dependent growth inhibitory effect on ConA-stimulated LCs and LBs. When treated with anti-FasL and anti-IL-10 blocking antibodies, the inhibitory effect of MSCs on LBs proliferation, and the effect of apoptosis induction on LBs decreased. Anti-TGF-[beta] blocking antibody treatment did not significantly influence MSCs. Therefore, the inhibitory effects of MSCs against activated LBs were significantly stronger than that against naïve LCs. FasL and IL-10, rather than TGF-[beta], play important roles in the immunosuppressive effects of MSCs. Copyright © 2008 John Wiley & Sons, Ltd.

•	Triacontanol works at a cellular level in Science paper
	Triacontanol increases the growth of plant cell cultures in-vitro. Reported in American Society of Plant Biologist publication. See... http://www.tiny.cc/CeGPW Or see.... http://www.plantphysiol.org/cgi/content/abstract/61/5/855 We know the effect the chemical triacontanol has on our in-vitro plant cultures from our own commercial laboratory work on plant tissue culture. We have been working 'secretly' with triacontanol for over 10 years. This was partly the reason why our plants grow so well...nobody could work out why our plants were better, stronger and grew quicker than the competition!) We then looked around for ways to bring this effect to a garden product. Finding a natural source of triacontanol we combined this with other products from our laboratory experience and this has resulted in the remarkable plant boosting product Triplantanol. We have seen it work well in the test tube and now anyone can see how well it works in the garden or on their plants.
