Cells harness the mechanical information reaching this anchorage to tune their phenotype during development and to coordinate their nuclear state with their microenvironment 9, 10. This trait depends not only on the mechanical properties of the different cytoskeletal networks, but also on their ability to be remodeled under stress, as well as the interaction between the cytoskeleton and the nucleus 7, 8.

The ability of cells to perceive and respond to physical stimuli exists throughout development. How these connections elicit a response from the nucleus depends on the phenotype of the cell and the cytokines it is exposed to in its local microenvironment 4, 5, 6. These connections allow cells to gather physical information about their surroundings using their cytoskeleton, and then relay it to the nucleus where it elicits physiological responses 1, 2, 3. The nucleus and cytoskeleton are physically connected in eukaryotic cells.

Finally, we offer a prospective basis to discriminate between stem cell types by coupling perinuclear mechanical properties to nuclear shape. Also, we find the pnCSK is a region with different mechanical properties than elsewhere in the cytoskeleton, with heterogeneously distributed locations exhibiting subdiffusive features, and which obeys physical relations conserved among various stem cell types. Here we show that nuclear shape is a quantifiable discriminant of mechanical properties in the perinuclear cytoskeleton (pnCSK) of various stem cell types. To address those questions, we combined two-dimensional particle-tracking microrheology and morphological measures using variable reduction techniques to measure whether cytoplasmic mechanics allow for discrimination between different human adherent stem cell types and across different culture conditions. Yet, how the mechanics of these connections vary inside stem cells is not fully understood. The ability of cells to proliferate, differentiate, transduce extracellular signals and assemble tissues involves structural connections between nucleus and cytoskeleton.
