This analysis also suggests that there is a minimal duration of the G1 phase, an observation that reproduces recent results in microchannels32. Indeed, for HT29-hgem, smaller cells showed a wider dispersion of G1 duration while larger cells tended to spend only a minimal time in G1 (about...
Asexual cells are normally able to reproduce entirely by themselves. But we have discovered that in about one-third of the dividing cells of Entamoeba invadens contraction of the cleavage furrow may stop before separation is complete. We... D Biron,P Libros,D Sagi,... - 《Nature》 被引量...
This mouse model reproduces pathogenic features of MS like perivascular inflammation and demyelination and is established by immunization of mice with recombinant myelin oligodendrocyte protein (rMOG). We histologically characterized plasma cell niches in the CNS and identified follicle-like structures ...
expressing migration stream which swings medially past the amygdalar anterior basolateral nucleus (E15.5), crosses the pallio-subpallial boundary (E16.5), and forms the NLOT2 within the anterior amygdala by E17.5. We conclude that theTbr1-expressing NLOT2 cells arise strictly within theposterior...
An alternative is to use adult SC (undifferentiated cells found in differentiated tissue that are able to proliferate, reproduce and differentiate into the specialized cell types of the tissues whence they were isolated) preferably obtained from the same patient, which would afford the advantage of ...
Because all the components of culture medium are defined, our culture conditions can constantly reproduce HPC-HCs. We have confirmed that our culture condition for proliferation of HPC-HBCs is capable of maintaining HPC-HBCs for at least 6 months. Our study showed that hPSC-HPCs cultured in ...
S1) and, intuitively, seem to become progressively more dormant as evidenced by increasing antibiotic tolerance (compare the data in Fig. 1 with those in Figs. 2a and S1–3). These physiological changes over time have direct biological impact. As an example, we could reproduce the previously ...
This strategy made it possible to reproduce what happens in vivo upon chemotherapy as accurately as possible. Indeed, after a phase of apoptosis, surviving PC3 cells set up a coordinated response to cope with the damage, recapitulating what occurs in tissues. In this process, they undergo ...
