IL-15 Protects NKT Cells from Inhibition by Tumor-Associated Macrophages and Enhances Antimetastatic Activity
IL-15 protected antigen-activated NKT cells from hypoxia, and transgenic expression of IL-15 in adoptively transferred NKT cells dramatically enhanced their antimetastatic activity in mice. [J Clin Invest]

Histone H1 Depletion Impairs Embryonic Stem Cell Differentiation
Investigators demonstrated that H1 plays a critical role in pluripotent stem cell differentiation, and their results suggest that H1 and chromatin compaction may mediate pluripotent stem cell differentiation through epigenetic repression of the pluripotency genes. [PLoS Genet]

Plasminogen Activator Inhibitor-1 Controls Bone Marrow Derived Cells Therapeutic Effect through MMP 9 Signaling: Role in Physiological and Pathological Wound Healing
Scientists assessed the role of PAI-1 and MMP9 in wound healing process and in the BMMNC related effects on physiological and pathological wound healing. [Stem Cells]
Abstract
Defining the Integration Capacity of ES Cell-Derived Photoreceptor Precursors
Researchers concluded that exclusion of proliferative cells from embryonic stem (ES) cell-derived cultures is essential for effective transplantation. Despite showing expression profiles characteristic of immature photoreceptors, the ES cell-derived precursors generated using this protocol did not display transplantation competence equivalent to precursors from the postnatal retina.

Abstract
Atoh1 Directs the Formation of Sensory Mosaics and Induces Cell Proliferation in the Postnatal Mammalian Cochlea In Vivo
Researchers found that Atoh1 induces ectopic sensory patches through Notch signaling to form a cellular mosaic similar to the endogenous sensory epithelia and expansion of the sensory mosaic through the conversion of supporting cells and nonautonomous supporting cell production. [J Neurosci]

Mixed Chimerism and Growth Factors Augment ß Cell Regeneration and Reverse Late-Stage Type 1 Diabetes
Researchers showed that combination therapy of induced mixed chimerism under a radiation-free nontoxic anti-CD3/CD8 conditioning regimen and administration of gastrin/epidermal growth factor augments both ß cell neogenesis and replication, resulting in reversal of late-stage type 1 diabetes in nonobese diabetic mice.

European Parliament Rebukes Three Regulatory Agencies
The European Parliament postponed signing off on the 2010 expenditures of three science-related E.U. agencies amid concerns over conflicts of interest and inappropriate spending. The vote to postpone the so-called discharge - which affects the European Food Safety Authority, the European Medicines Agency, and the European Environment Agency - has no immediate consequences, but it is seen as a warning that the agencies need to restore their credibility.
