Overview

Also Known As:129S1

129 mice are widely used in the production of targeted mutations due to the availability of multiple embryonic stem cell lines derived from them. They also have a high incidence of spontaneous testicular teratomas.

Detailed Description

Historically, the 129 inbred mice are known for the high incidence of spontaneous testicular teratomas, though the incidence differs between substrains (1-3% in 129 parental substrains; 30% in teratoma substrains.) More recently, 129 mice are widely used in the production of targeted mutations due to the availability of multiple embryonic stem cell lines derived from them. There is major genetic variation within the 129 "family", which has led to an update of the nomenclature and a division of the substrains into three major groups: parental substrains (129P), steel substrains (129S) and "teratoma" substrains (129T). Investigators using 129 substrains for targeted mutagenesis should be careful in the selection of the appropriate 129 substrain to match the embryonic stem cell line. For a complete history of the numerous 129 substrains, see Simpson, et al., 1997.

In 2019-2020, researchers at The Jackson Laboratory discovered this inbred strain contains the Trem2^S148E allele - a naturally occurring variant at position 48351151-48351152 on Chr 17 (rs108080490 and rs107649577; Ensembl GRCm38.p6). This TC to GA transition results in a serine to glutamic acid substitution at amino acid 148 (S148E).

Development

129S1/SvImJ was developed to serve as a control inbred strain for many of the steel-derived ES cell lines (e.g. W9.5 and CJ7). SSLP marker analysis indicates that 129S1/SvImJ is identical to 129S1/Sv +^Oca2-p +^Tyr-c Kitl^Sl-J/+ except for the region surrounding the Kitl gene on Chr 10. 129S1/SvImJ was derived from 129S1/Sv-+^Oca2-p +^Tyr-c Kitl^Sl-J/+ (Stock No.
000090). The steel-Jackson mutation (Kitl^Sl-J, formerly Mgf^Sl-J), is segregating in Stock No. 000090. Kitl^Sl-J was removed in 1995, at F26, by selective breeding to produce 129/Sv-+^Oca2-p +^Tyr-c +^Kitl-SlJ (Stock No. 002448, see Simpson et al., 1997). This name was later shortened to simply 129/SvImJ. Subsequently designated 129S3/SvImJ (Festing et al., 1999), this strain was renamed 129S1/SvImJ in February, 2001 to emphasize its relationship to Stock No. 000090.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
