Allogeneic and xenogeneic lymphoid reconstitution in a RAG2(-/-)IL2RG(y/-) severe combined immunodeficient pig: A preclinical model for intrauterine hematopoietic transplantation

FRONTIERS IN VETERINARY SCIENCE, 9.

By: R. Sper n, J. Proctor n, O. Lascina n, L. Guo n, K. Polkoff n, T. Kaeser n, S. Simpson n, L. Borst n ...

author keywords: severe combined immunodeficiency; pig; xenotransplantation; allotransplantation; hematopoietic; RAG2; IL2RG; transgenic
TL;DR: The data shows that the pig thymus provides a microenvironment conducive to engraftment, survival and development of human T-cells and provides evidence that the developing T-cell compartment can be populated to a significant extent by human cells in large animals. (via Semantic Scholar)

Patch grafting, strategies for transplantation of organoids into solid organs such as liver

BIOMATERIALS, 277.

By: W. Zhang*, G. Lanzoni*, H. Hani*, D. Overi*, V. Cardinale*, S. Simpson n, W. Pitman*, A. Allen* ...

author keywords: Liver; Biliary tree; Stem/progenitors; Cell therapies; Grafting; Matrix-metalloproteinases (MMPs); Hyaluronans
MeSH headings : Animals; Cell Differentiation; Hepatocytes; Liver; Organoids; Stem Cells; Swine
TL;DR: RNA-seq analyses revealed that engraftment correlated with expression of matrix-metalloproteinases (MMPs), especially secreted isoforms that were found expressed strongly by organoids, less so by MSCs, and minimally, if at all, by adult cells. (via Semantic Scholar)

In Vitro Validation of Transgene Expression in Gene-Edited Pias Using CRISPR Transcriptional Activators

CRISPR JOURNAL, 3(5), 409–418.

By: K. Polkoff n, J. Chung n, S. Simpson*, K. Gleason n & J. Piedrahita n

MeSH headings : Animals; Animals, Genetically Modified / genetics; CRISPR-Associated Protein 9 / genetics; CRISPR-Associated Protein 9 / metabolism; Cells, Cultured; Clustered Regularly Interspaced Short Palindromic Repeats; Gene Editing / methods; Gene Expression; Nuclear Transfer Techniques; RNA, Guide, Kinetoplastida / genetics; RNA, Guide, Kinetoplastida / metabolism; Swine; Trans-Activators / genetics; Trans-Activators / metabolism; Transgenes
TL;DR: It is shown that CRISPR-dCas9 transcriptional activators can be used to validate functional transgene insertion in nonexpressing easily cultured cells such as fibroblasts and is a tool that could be used across disciplines and animal species to save time and resources by verifying expected outcomes of gene edits before generating live animals.

High mobility group A2 (HMGA2) deficiency in pigs leads to dwarfism, abnormal fetal resource allocation, and cryptorchidism

Proceedings of the National Academy of Sciences, 115(21), 5420–5425.

By: J. Chung n, X. Zhang n, B. Collins n, R. Sper n, K. Gleason n, S. Simpson n, S. Koh n, J. Sommer n ...

author keywords: HMGA2; dwarfism; swine; gene editing; organ size
