Es que me habías colgado el enlace de otro lado. Ah, sí, y el partner en plaquetas saldrá en breve, aunque ya prácticamente sabemos quién es. Es un productor de plaquetas pequeñajo pero sólido y al que le va a caer una financiación gorda gubernamental en breve.
Hala, ya que estamos, pongo el resumen completo
Cell-based therapies, such as adult tissue-derived mesenchymal stromal cells (MSCs) are showing promise in small clinical trials for systemic lupus erythematosus (SLE). However, the inability to manufacture large scale quantities from a single donor without compromising functionality limits their utility while the use of multiple donors leads to variability in MSC quality. Hemangio-mesenchymal cells (HMCs), which have immunomodulatory properties similar to MSCs but are derived from a virtually inextinguishable human embryonic stem cell (hESC) source, can circumvent issues regarding scalability and consistent quality. Here, we show that HMCs have therapeutic utility in SLE; they extend the survival of lupus-prone NZB x NZW F1 (also referred to as BWF1) mice by preventing progression of their otherwise fatal lupus nephritis (LN). HMC treatment led to statistically significant reductions in proteinuria and serum creatinine. They preserved renal architecture and prevented interstitial inflammation and protein cast formation. HMC treatment led to significant reductions in the circulating levels of tumor necrosis alpha (TNFα) and interleukin 6 (IL-6), two inflammatory cytokines implicated in SLE progression. Mechanistically, in vitro data support these findings as co-culture of HMCs with lipopolysaccharaide (LPS)-stimulated BWF1 lymphocytes decreased the secretion of TNFα and IL-6 into the culture supernatant. Moreover, co-culture of HMCs enhanced the percentage of regulatory T cells in the BWF1 lymphocyte pool. Collectively, these results suggest that HMC immunomodulatory capabilities are therapeutically useful and represent an important step in the development of a commercially scalable and efficacious cell-based treatment for SLE/LN.
