Ten million apoptotic Hmgb/ fibroblasts and a control population of non-apoptotic ones were resuspended in 50 l PBS containing 0.32 M sucrose, 0.5% NP-40 and 1 M bacterially produced HMGB1, either fluorescently labelled with Cy5 (Pharmacia) or unlabelled6MPO/ALT ratios indicate inflammatory cell recruitment normalized to liver damage1 c)[0064] Hmgb/ fibroblasts were treated with 2 ng/ml hTNF-alpha and 35 M cycloheximide[0081] Cells in RPMI alone did not divide, while cells in RPMI plus HMGB1 divided actively for at least 24 hours, and then more slowly due to nutrient exhaustionthe filters were removed, and the result was evaluated as described for the chemotaxis assay11A), suggesting that HMGB1 caused considerable muscle inflammationAfter 8 hours at 37 CHeLa cells and fibroblasts (line VA1, Hmgb1+/+, and line C1, Hmgb1/) were grown as described (Calogero et al., Nature Genet


Embryonic fibroblasts obtained from Hmgb1/ and Hmgb1+/+ mice Calogero et al., Nature Genet., 22, 276-280, 1999) were equally susceptible to apoptosis (not shown), indicating that freezing of HMGB1 onto chromatin is a consequence of apoptosis, but not a requisiteHMGB1-stimulated D16 cells had a normal morphology and excluded Trypan blue up to the end of the experiment, whereas cells in control cultures without HMGB1 were dying (not shown)[0096] D16 cells were seeded in RPMI medium with 20% FCS and then starved for 16 hours in the absence of serum to synchronize the cell populationChemotaxis assays were performed using modified Boyden chambers10 HMGB1 induces the transit of mesoangioblasts through an endothelial monolayer


[0097] The authors investigated in more detail the proliferative response of D16 cells to HMGB1: cells were exposed for 6, 12, and 24 hours to RPMI medium alone (negative control), or medium containing 30 ng/ml HMGB1 or 20% FCS, and analyzed for DNA content by FACS after propidium iodide staining[0094] Heparin beads (a slurry containing 3 g beads in 20 l PBS), either laoded with HMGB1 or not, were injected with an insulin syringe into tibialis anterior muscles of 6-week old female CD-1 mice (3 per group)Full length HMGB1, boxes A and B, the didomain AB, and tailless HMGB1 (ABbt) are represented in (C)JThe authors then tested whether HMGB1 could also stimutate stem cell proliferation
