Long-term phenotypic characterization of human bone marrow and adipose tissue derived mesenchymal stromal cells  [PDF]
Dean L. Glettig, David L. Kaplan
Stem Cell Discovery (SCD) , 2013, DOI: 10.4236/scd.2013.32015

We present methods to characterize mesenchymal stromal cells (MSC) over long time periods in vitro. The methods entail passaging cells multiple times and performing differentiation studies with the cells at each passage. Using an array of surface markers and flow cytometric quantification, the data can be correlated to traditional measures of differentiation such as PCR and staining. Using these methods to quantify the amount of differentiation, we concluded that many common MSC markers do not specifically define MSCs with true stem cell properties. Additionally, adipose-derived as opposed to bone marrow-derived MSCs show long-term CD34+ labeling. The methods described can be used to help identify stem cell markers and to characterize the state of stem cells in vitro. Compiling these data from multiple laboratories would be helpful to determine source, extraction and culture methods needed to obtain high yields of useful stem cells.

More Effective Field Theory for Nonrelativistic Scattering
David B. Kaplan
Physics , 1996, DOI: 10.1016/S0550-3213(97)00178-8
Abstract: An effective field theory treatment of nucleon-nucleon scattering at low energy shows much promise and could prove a useful tool in the study of nuclear matter at both ordinary and extreme densities. The analysis is complicated by the existence a large length scale --- the scattering length --- which arises due to couplings in the short distance theory being near critical values. I show how this can be dealt with by introducing an explicit s-channel state in the effective field theory. The procedure is worked out analytically in a toy example. I then demonstrate that a simple effective field theory excellently reproduces the 1S_0 np phase shift up to the pion production threshold.
Power Counting and the Renormalization Group for an Effective Description of NN Scattering
David B. Kaplan
Physics , 1998,
Abstract: I outline the power counting scheme recently introduced by M. Savage, M. Wise and myself for the effective field theory treatment of nucleon-nucleon scattering. It is particularly useful for describing systems with a large scattering length, and differs from Weinberg's power counting. A renormalization group analysis plays a big role in determining the order of a given operator. Pions are ignored in this discussion; how to incorporate them is discussed in M. Savage's talk, nucl-th/9804034.

Effective Field Theory for Nuclear Physics
David B. Kaplan
Physics , 1999, DOI: 10.1016/S0375-9474(99)00583-7
Abstract: I summarize the motivation for the effective field theory approach to nuclear physics, and highlight some of its recent accomplishments. The results are compared with those computed in potential models.
Effective field theory as the bridge between lattice QCD and nuclear physics
David B. Kaplan
Physics , 2006, DOI: 10.1063/1.2714346
Abstract: A confluence of theoretical and technological developments are beginning to make possible contributions to nuclear physics from lattice QCD. Effective field theory plays a critical role in these advances. I give several examples.

Electroweak Baryogenesis
David B. Kaplan
Physics , 1995,
Abstract: Baryogenesis during the electroweak phase transition is a plausible scenario for for the origin of matter in the Universe. Furthermore, it has the advantage over other scenarios in that one can imagine that much of the physics involved may be experimentally probed before long. In the past year a consensus has developed about major mechanisms involved. In this talk I give an overview of the standard picture, and discuss briefly the advances over the past year that suggest electroweak baryogenesis is a robust phenomenon.
