3Current evidence on potential of adipose derived stem cells to enhance bone regeneration and future projection显示文摘Injuries to the postnatal skeleton are naturally repaired through successive stepsinvolving specific cell types in a process collectively termed “bone regeneration”.Although complex, bone regeneration occurs through a series of well-orchestratedstages wherein endogenous bone stem cells play a central role. In most situations,bone regeneration is successful;however, there are instances when it fails andcreates non-healing injuries or fracture nonunion requiring surgical or therapeuticinterventions. Transplantation of adult or mesenchymal stem cells (MSCs) definedby the International Society for Cell and Gene Therapy (ISCT) as CD105+-CD90+CD73+CD45-CD34-CD14orCD11b-CD79αorCD19-HLA-DR- is beinginvestigated as an attractive therapy for bone regeneration throughout the world.MSCs isolated from adipose tissue, adipose-derived stem cells (ADSCs), aregaining increasing attention since this is the most abundant source of adult stemcells and the isolation process for ADSCs is straightforward. Currently, there isnot a single Food and Drug Administration (FDA) approved ADSCs product forbone regeneration. Although the safety of ADSCs is established from their usagein numerous clinical trials, the bone-forming potential of ADSCs and MSCs, ingeneral, is highly controversial. Growing evidence suggests that the ISCT definedphenotype may not represent bona fide osteoprogenitors. Transplantation of bothADSCs and the CD105- sub-population of ADSCs has been reported to induce bone regeneration. Most notably, cells expressing other markers such as CD146,AlphaV, CD200, PDPN, CD164, CXCR4, and PDGFRα have been shown torepresent osteogenic sub-population within ADSCs. Amongst other strategies toimprove the bone-forming ability of ADSCs, modulation of VEGF, TGF-β1 andBMP signaling pathways of ADSCs has shown promising results. The U.S. FDAreveals that 73% of Investigational New Drug applications for stem cell-basedproducts rely on CD105 expression as the “positive” marker for adult stem cells.A concerted effort involving the scientific community, clinicians, industries, andregulatory bodies to redefine ADSCs using powerful selection markers andstrategies to modulate signaling pathways of ADSCs will speed up thetherapeutic use of ADSCs for bone regeneration.Quang Le Vedavathi Madhu Joseph M Hart Charles R Farber Eli R Zunder Abhijit S Dighe Quanjun Cui 2021World Journal of Stem Cells2021,13,9:2

5Competition between fusion-evaporation and multifragmentation in central collisions in ^(58)Ni+^(48)Ca at 25A MeV显示文摘The experimental data concerning the58Ni+48Ca reaction at Elab(Ni)=25A MeV,collected by using the CHIMERA 4π device,have been analyzed in order to investigate the competition among different reaction mechanisms for central collisions in the Fermi energy domain.As a main criterion for centrality selection we have chosen the flow angle(flow) method,making an event-by-event analysis that considers the shape of events,as it is determined by the eigenvectors of the experimental kinetic-energy tensor.For the selected central events(flow >60°) some global variables,good to characterize the pattern of central collisions have been constructed.The main features of the reaction products were explored by using different constraints on some of the relevant observables,like mass and velocity distributions and their correlations.Much emphasis was devoted,for central collisions,to the competition between fusion-evaporation processes with subsequent identification of a heavy residue and a possible multifragmentation mechanism of a well defined(if any) transient nuclear system.Dynamical evolution of the system and pre-equilibrium emission were taken into account by simulating the reactions in the framework of transport theories.Different approaches have been envisaged(dynamical stochastic BNV calculations + sequential SIMON code,QMD,CoMD,etc.).Preliminary comparison of the experimental data with BNV calculations shows reasonable agreement with the assumption of sequential multifragmentation emission in the mass region of IMFs close to the heavy residues.Possible deviations from sequential processes were found for those IMFs in the region of masses intermediate between the mass of heavy residues and the mass of light IMFs.Further simulations are in progress.The experimental analysis will be enriched also by information obtained inspecting the IMF-IMF correlation function,in order to elucidated the nature of space-time decay property of the emitting source associated with events having the largest IMF multiplicity.FRANCALANZA L ABBONDANNO U AMORINI F BARLINI S BINI M BOUGAULT R BRUNO M CARDELLA G CASINI G AGOSTINO M D' De FILIPPO V De SANCTIS J GERACI E GIUSSANI A GRAMEGNA F GUIOT B KRAVCHUK V La GUIDARA E LANZALONE G Le NEINDRE N MAIOLINO C MARINI P MORELLI L OLMI A PAGANO A PAPA M PIANTELLI S PIRRONE S POLITI G POGGI G PORTO F RUSSOTTO P RIZZO F VANNINI G VANNUCCI L 2013Nuclear Science and Techniques2013,24,5:2
