TL;DR: It is shown that an early HSC population that might reside in the low-oxygenic niche can be functionally isolated by taking advantage of the relative intracellular ROS activity and treatment with an antioxidant, a p38 inhibitor, or rapamycin was able to restore HSC function in the ROS(high) population.

TL;DR: It is found that overexpression of mutant, Ca2+ -insensitive calmodulin (CaM) ablates Ca2- -dependent inactivation in a "dominant-negative" manner, demonstrating that CaM is the actual Ca 2+ sensor for inactivation and suggesting that Ca M is constitutively tethered to the channel complex.

TL;DR: In vivo magnetic resonance tracking of magnetically labeled cells is feasible in humans for detecting very low numbers of dendritic cells in conjunction with detailed anatomical information and appears clinically safe and well suited to monitor cellular therapy in humans.
Abstract: The success of cellular therapies will depend in part on accurate delivery of cells to target organs. In dendritic cell therapy, in particular, delivery and subsequent migration of cells to regional lymph nodes is essential for effective stimulation of the immune system. We show here that in vivo magnetic resonance tracking of magnetically labeled cells is feasible in humans for detecting very low numbers of dendritic cells in conjunction with detailed anatomical information. Autologous dendritic cells were labeled with a clinical superparamagnetic iron oxide formulation or (111)In-oxine and were co-injected intranodally in melanoma patients under ultrasound guidance. In contrast to scintigraphic imaging, magnetic resonance imaging (MRI) allowed assessment of the accuracy of dendritic cell delivery and of inter- and intra-nodal cell migration patterns. MRI cell tracking using iron oxides appears clinically safe and well suited to monitor cellular therapy in humans.

TL;DR: Observations provide a potential mechanism involving MAP kinase activation in osteogenic differentiation of adult stem cells and suggest that commitment of hMSCs into osteogenic or adipogenic lineages is governed by activation or inhibition of ERK, respectively.

TL;DR: Examination of “preimmune” serum samples from a patient who progressively developed the symptoms of scleroderma CREST over a period of several years shows that these patients make antibody species recognizing at least three distinct epitopes on C ENP-B and two on CENP-C.
Abstract: We have examined "preimmune" serum samples from a patient who progressively developed the symptoms of scleroderma CREST over a period of several years. During this period, anti-centromere antibodies (recognized by indirect immunofluorescence) appeared in the serum. Concomitant with the appearance of the anti-centromere antibodies, antibody species recognizing three chromosomal antigens in immunoblots of SDS polyacrylamide gels appeared in the patient's serum. These antigens migrate with electrophoretic mobilities corresponding to Mr = 17, 80, and 140 kilodaltons (kd). Affinity-eluted antibody fractions recognizing the antigens have been prepared from sera of three other patients. Indirect immunofluorescence labeling of mitotic cells using these antibody fractions demonstrates that the antigens are centromere components. We designate them CENP (CENtromere Protein) - A (17kd), CENP-B (80kd), and CENP-C (140kd). The three CENP antigens share antigenic determinants. Immunoblotting experiments show that these patients make antibody species recognizing at least three distinct epitopes on CENP-B and two on CENP-C. Sera from different patients contain different mixtures of the antibody species.
