The cells that survive are selected for gene transformation, which Dale accomplishes by making clever use of a common soil bacterium, Agrobacterium tumefaciens.
Administered together, Lu's bacteriophage and antibiotics have the potential to eliminate nearly 30,000 times more bacteria than antibiotics alone, including cells that survive antibiotic-only treatment.
IMPORTANCE: In the absence of resistant mutants, infection reoccurrences can still occur because of persisters, rare bacterial cells that survive antibiotic treatments to repopulate infection sites.
d, In the defined protocol, only the combination of BMP4 and RA treatment yielded enough p63 expression to produce cells that survive in keratinocyte selection medium (n = 3).
In the anoxic microenvironment beneath the fibrous, bloodless capsule, any malignant cells that survive become increasingly unstable and virulent, like superroaches proliferating in the wake of a pesticide bomb.
Some cells that survive the initial injury may die days, weeks, or months later, when mechanisms inside the nucleus of the cell trigger a breakdown of its DNA.
Cancer specialists have long noticed that cancer cells that survive therapy are often more aggressive than those that were killed off, and that treated tumors regrow much faster than untreated ones.
Using ssDNA it is possible to achieve recombination frequencies of over 50% of the cells that survive electroporation; thus, a selection is not necessary for finding the desired mutations.
Host CD4+ T cells that survive sublethal or even lethal preconditioning regimens can participate in the process of hematopoietic stem cell graft rejection, particularly when the transplantations are performed across a major histocompatibility complex (MHC) class II barrier.
The cells that survive have an opportunity to mutate and become the next-generation cancer cells.
It demonstrates a high degree of osteoinduction from surface osteoblasts in the host bone, circulating osteoprogenitor cells and donor cells that survive transplantation.
