The Vacanti mouse. The Vacanti mouse was a laboratory mouse (circa 1996) [1] that had what looked like a human ear grown on its back. The "ear" was actually an ear-shaped cartilage structure grown by seeding cow cartilage cells into biodegradable ear-shaped mold and then implanted under the skin of the mouse, with an external ear-shaped splint to maintain the desired shape.
Vacanti claimed that February to have replicated the effect in human skin fibroblast cells, [24] and said "We believe that this is exactly what happens in the body during attempts to repair any damaged or diseased tissue". [25] Vacanti said in 2012 he had used the technique to grow a replacement trachea using autologous cells from a patient. [23]
In human newborns, the inner ear is fully mature. Thus, hair cell loss results in loss of hearing at any postnatal stage. The adult mammalian inner ear lacks the capacity to divide or regenerate spontaneously hair cells. [27] This is to say that neither direct transdifferentiation nor mitotic division have the innate ability to restore hair cells.

The NOD-SCID mouse is considered more immunodeficient than the nude mouse, and therefore is more commonly used for PDX models because the NOD-SCID mouse does not produce natural killer cells. [ 3 ] When human tumors are resected, necrotic tissues are removed and the tumor can be mechanically sectioned into smaller fragments, chemically digested ...
