Sentences with phrase «mimicking embryonic cells»

Salk scientists and colleagues have proposed new molecular criteria for judging just how close any line of laboratory - generated stem cells comes to mimicking embryonic cells seen in the very earliest stages of human development, known as naïve stem cells.

Now, a collaborative team of scientists at Washington University in St. Louis has developed a new process to generate NP - like cells from hiPSCs, one that truly goes back to the beginning and mimics the process of embryonic development.

Yamanaka's group and two others followed up earlier this year with firmer evidence that these induced pluripotent stem (iPS) cells faithfully mimicked the patterns of gene activity and cellular differentiation observed in embryonic stem cells.

Instead of mimicking the complex 3D organization of the developing pituitary gland, this approach relies on the precisely timed exposure of human pluripotent stem cells to a few specific cellular signals that are known to play an important role during embryonic development.

When current methods for generating naïve stem cells in the lab were judged using the three tests, each fell short of mimicking the naïve embryonic cells in different ways.

Since human embryonic stem cells grow in an adherent culture system, for cells being reprogrammed this «new culture system» is an adherent culture system (to try and mimic the conditions the embryonic stem cells want to be happy).

But the eyebrow - raising reports claimed that adult stem cells sometimes behave like their embryonic counterparts, mimicking their trademark capacity to engender all types of cells — an ability dubbed pluripotency.
