Objective : The acute loss of myocytes during infarction increases loading conditions, which in turn triggers adverse remodeling of infarcted, adjacent and remote regions. Late Gadolinium Enhancement (LGE) cardiac MRI (CMR) can distinguish these regions and thus determine the effect of bone marrow progenitor cell (BMC) therapy on regional remodeling and function. Methods : 47 patients from the REPAIR AMI trial who underwent CMR at baseline and 12 month were evaluated in a segment by segment fashion according to the AHAs 17 segment model, defining LGE positive segments as infarcted and LGE negative segments as adjacent or remote. We measured enddiastolic wall diameters (WD) and wall thickening (WT) at 0 and 12 month by serial MRI. Results : WD decreased in all patients and all segments with a tendency to smaller diameters in BMC treated patients. In the prespecified subgroup of patients with larger infarcts (EF below the median of 48.9%) we observed a positive effect on adverse remodeling in BMC patients not only in infarcted but also in the remote areas. Infarcted segments showed a decrease in WD of 21.9% ± 4.0 SE in the BMC group vs. 8.5% ± 3.4 in the Placebo Group p=0.02. In BMC patients WD decreased in remote segments by 8.1% ± 4.4 SE compared to 4.9% ± 3.3 SE in the Placebo group, p=0.03. This effect on remodeling translates into a functional benefit. In remote segments WT decreases in both gropus but significantly so only in Placebo patients (BMC-7.8% ± 5.4 p= 0.2 vs. Placebo −13.9% ± 4.4 p=0.002, p for interaction 0.4). The largest effect was observed in the infarcted segments where BMC therapy led to an increase in WT of 26.6% ± 5.1 SE compared to Placebo 0.7% ± 4.6 SE p= 0.0001. The positive effect is mediated by wall diameters, regression analysis shows a significant inverse relationship between WD and WT, p = 0.0001 Conclusion : BMC therapy effectively prevents adverse remodeling not only in the infarct zone but also in remote segments for patients with large infarcts resulting in increased contractility. This seems to be mediated by a positive effect on enddiastolic wall geometry yielding smaller wall diameters.

Abstract A primitive human hematopoietic myeloid progenitor cell line, KG1a, characterized by high expression of the CD34 surface antigen has been observed to extend long, thin pseudopodia. Once extended, these pseudopods may take on one of two newly described morphologies, tenupodia or magnupodia. Tenupodia are very thin and form in linear segments. They adhere to the substrate, can bifurcate multiple times, and often appear to connect the membranes of cells more than 300 μm apart. Magnupodia are much thicker and have been observed to extend more than 330 μm away from the cell. Magnupods are flexible and can exhibit rapid dynamic motion, extending or retracting in a few seconds. During retraction, the extended material often pools into a bulb located on the pod. Both morphologies can adhere to substrates coated with fibronectin, collagen IV, and laminin as well as plastic. The CD34 and CD44 antigens are also present on the surface of these podia. Primary human CD34+ cells from fetal liver, umbilical cord blood, adult bone marrow, and mobilized peripheral blood extend these podia as well. The morphology that these pseudopods exhibit suggest that they may play both sensory and mechanical roles during cell migration and homing after bone marrow transplantation.
