Concerning this process, a variety of different polymers can be electrospun to generate either synthetic, natural, or as a combination of both composite nanofibers.
Why certain stimuli trigger ferroptosis instead of another form of cell death, and whether this process could be adaptive in vivo, are two major unanswered questions concerning this process.
However, little is known concerning this process in the obligate intracellular pathogen and model for reductive evolution, Rickettsia prowazekii.
However, more detailed mechanisms concerning this process are still under investigation.
Knowledge concerning this process, as summarized in details by Parfitt, has with some exceptions [ 2, 9, 10, 12, 22- 25], disappeared from the current texts [ 22, 26].
To gain insight concerning this process we used THP-1 macrophages infected with M. abscessus, M. fortuitum, M. celatum, and M. tuberculosis.
Finally, even if our data show a dose-dependent increase of spindle multipolarisation, associated with aberrant chromosomes behaviour in both PSP and CC sublines after paclitaxel treatment, no significant difference concerning this process was found between the two sublines group.
Nonetheless, many questions concerning this process remain unanswered, such as whether the dual regulatory mechanism of Pou3f1 is also utilized to initiate the mouse neural program in vivo, whether this two-way modulating processes occurs simultaneously or in a sequential, temporal manner, and how the controversial activation/inhibition activities of the Pou3f1 transcription factor is achieved.
Key to the study of GBM invasion is the availability of a reliable culture system, in order to preserve the tumorigenic potential of cells derived from patients, and of "in vivo" models suitable to address questions and test hypothesis concerning this process.
