The Equilibria in Lipid–Lipoic Acid Systems: Monolayers, Microelectrophoretic and Interfacial Tension Studies

Molecules, 2020
In this examination, we investigated the effect of lipoic acid (LA) on the properties of biological membrane models (monolayers, bilayers, and liposomes) formed from phosphatidylcholine (PC) or phosphatidylserine (PS) using the Langmuir ...

Synthetic self-patterning and morphogenesis in mammalian cells: a proof-of-concept step towards synthetic tissue development

Engineering Biology, 2017
This study reports a proof-of-concept study as a step toward synthetic-biological morphogenesis of tissues. Events in normal animal development usually follow the sequence: patterning → differential gene expression → morphogenesis. A synthetic biological

Comparison of Germ Cell Gene Expressions in Spontaneous Monolayer versus Embryoid Body Differentiation of Mouse Embryonic Stem Cells toward Germ Cells [PDF]

International Journal of Fertility and Sterility, 2019
Background Genetic and morphologic similarities between mouse embryonic stem cells (ESCs) and primordial germ cells (PGCs) make it difficult to distinguish differentiation of these two cell types in vitro. Using specific GC markers expressed in low level
