Creating liver-like tissue from spleen
The liver is an organ that can be transplanted from a living donor to a recipient. The liver is capable of regeneration. Any method that expands the supply of liver tissue ex vivo could prove useful.
A novel experiment was performed by Wang L. et al. A mouse spleen was modified to support the creation of spleen tissue. Tumor extract was injected into a spleen to create a pro-generative and immuno-suppressive environment. Liver cells were implanted, ultimately proliferating. The source were autologous, allogeneic, and xenogeneic. Functional tests demonstrated that the liver-like tissue embedded in the spleen were functional.
Could these experimental set up be used to foster the growth of human liver tissue?
