A perylene-based probe was developed for uridine diphosphate (UDP) sensing and cell imaging. The probe presented about 4-fold fluorescence enhancement in the presence or absence of 100equiv UDP. The selectivity toward UDP over other phosphor-containing anions was observed. The selective UDP sensing was speculated to be related to the binding affinities of Zn(2+) ions in sensor with the uridine and phosphate moieties of UDP. Furthermore, this probe was also applied to image of UDP in living cells.

Migrasome formation is initiated preferentially in tubular junctions by membrane tension.

Migrasomes, the vesicle-like membrane micro-structures, arise on the retraction fibers (RFs), the branched nano-tubules pulled out of cell plasma membranes during cell migration and shaped by membrane tension. Migrasomes form in two steps: a local RF bulging is followed by a protein-dependent stabilization of the emerging spherical bulge. Here we addressed theoretically and experimentally the previously unexplored mechanism of bulging of membrane tubular systems.

Prime Editing can rewrite genes in living cells by allowing point mutations, deletions, or insertion of small DNA sequences with high precision. However, its safe and efficient delivery into human stem cells remains a technical challenge. In this report, we engineer Nanoscribes, virus-like particles that encapsidate ribonucleoprotein complexes of the Prime Editing system and allow their delivery into recipient cells.

Detecting changes of testicular interstitial cell membranes with a fluorescent probe after incubation and cryopreservation with cryoprotective agents.

Membrane alterations are among central factors predetermining cell survival during cryopreservation. In the present research, we tested some serum-/xeno-free cryoprotective compositions including dimethyl sulfoxide (MeSO) and polymers for their osmotic impact and toxicity towards testicular interstitial cells (ICs). IC survival was determined after their contact with MeSO, dextran (D40), hydroxyethyl starch (HES), polyethylene glycols (PEG1500 and PEG400), or after cryopreservation and cryoprotective agent (CPA) removal.
