…on Faculty Research: Stem Cell Shu Chien University Professor & Chair Dr. Chien and his colleagues have developed an array system 〈with thousands of combinations〉 that allows the rapid determination of the optimum physical and chemical conditions that direct the differentiation of stem cells into specific cell types. The ability…

A multidisciplinary team has found the underlying mechanisms controlling the size of cells. The researchers found that “the adder,” a function that guides cells to grow by a fixed added size from birth to division, is controlled by specific proteins that accumulate to a specific threshold.

Bioengineers at UC San Diego have shown that human-genome produced RNA is present on the surface of human cells, suggesting a more expanded role for RNA in cell-to-cell and cell-to-environment interactions than previously thought.

A new mathematical model predicts that mammalian sperm cells have two distinct swimming modes. This prediction opens new questions about potential connections between sperm cells’ motor activity and their transitions to hyperactivation phases that may play an important role in fertilization.

…like the bones that hold up your body, your cells have their own scaffolding that holds them up. This scaffolding, known as the extracellular matrix, or ECM, not only props up cells but also provides attachment sites, or “sticky spots,” to which cells can bind, just as bones hold muscles…

Nearly every cell in our bodies carries the same genetic code. Yet different types of cells read the same DNA in widely different ways, influenced by chemical chemical tags that modify the genetic material without changing the underlying DNA sequence. Scientists today announced significant progress in the unraveling of the…
