Science with the space-based interferometer LISA. IV: probing inflation with gravitational waves
We investigate the potential for the LISA space-based interferometer to
detect the stochastic gravitational wave background produced from different
mechanisms during inflation. Focusing on well-motivated scenarios, we study the
resulting contributions from particle production during inflation, inflationary
spectator fields with varying speed of sound, effective field theories of
inflation with specific patterns of symmetry breaking and models leading to the
formation of primordial black holes. The projected sensitivities of LISA are
used in a model-independent way for various detector designs and
configurations. We demonstrate that LISA is able to probe these well-motivated
inflationary scenarios beyond the irreducible vacuum tensor modes expected from
any inflationary background.Comment: 53 pages, 18 figures; v2: minor changes to match published versio
Defining the risks of mesenchymal stromal cell therapy
We address the issue of the potential for malignant transformation of cultured mesenchymal stromal cells (MSC) commonly used in clinical cell-therapy protocols and describe the culture conditions under which tumorigenesis is likely to be an extremely uncommon event.Stemcel biology/Regenerative medicine (incl. bloodtransfusion
