In sharp distinction to the classical tissue engineering conception, it does not contemplate the creation in vitro or in situ of a living tissue, but the induction of healing and adaptive remodeling through host's cell engraftment and natural physiological conditioning (body as a bioreactor).
Critically, ETS factors also play roles under pathological conditions, such as leukemia and, therefore, deciphering their mechanism of action will not only enhance our knowledge of normal hematopoiesis, but also inform protocols for their creation in vitro from pluripotent stem cells and the design of new therapeutic approaches for the treatment of malignant blood cell diseases.
The creation of in-vitro meat does require the slaughter of animals, but the point is that, in theory, a single specimen could provide the seed material for hundreds of tonnes of meat.
In vitro fertilization similarly necessitates the creation and destruction of dozens of embryos, without eliciting much government discussion or public outcry.
For decades, many countries have permitted human embryos to be studied in the laboratory only up to 14 days after their creation by in vitro fertilization.
In the present study, we report the use of in vitro directed evolution for the creation of a new l-ASNase variant lacking glutaminase activity.
This review highlights progress in the creation of in vitro functional microvessel networks, and emphasizes organ-specific functional and structural characteristics that should be considered in the future mimicry of four organ systems that are of primary interest: lung, brain, liver, and muscle (skeletal and cardiac).
The creation of in vitro functional hepatic tissue simulating micro-environmental niche of native liver is a keen area of research due to its demand in bioartificial liver (BAL) and cell-based tissue engineering.
Growing three-dimensional (3D) scaffolds that contain more than a few layers of seeded cells in vitro is crucial for the creation of thick and viable cardiac tissues in vivo.
