Expression of CRE recombinase in the mesoblast lineage driven by the hlh-8 promoter. heSi143 rescues fzr-1(ku298). fzr-1 will be excised upon mesoblast-specific expression of CRE, creating a mesoblast specific mutant of fzr-1. This recombination event can be visualized by a switch from red to green in those cells (the mesoblast) were fzr-1 is lost. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

Maintain at 15-25C. heIs145 expresses a read-out construct used to visualize CRE activity and specificity, and to test whether CRE expression is likely to induce loss of a gene of interest (tagBFP in this case) in a given tissue. Expression of CRE will result in a change from mCherry to GFP and loss of tagBFP expression in those cells where CRE is active. Reference: Ruijtenberg S & van den Heuvel S.

Maintain the line at 15C and shift to 25C for mutant analysis. Expression of CRE recombinase in the mesoblast lineage driven by the hlh-8 promoter. heSi164 carries a swsn-1 rescue construct which ensures rescue of the temperature-sensitive swsn-1(os22) mutation. Upon expression of CRE (in this case in the mesoblast lineage) the swsn-1 gene will be excised, creating a mesoblast specific mutant of swsn-1. This recombination event can be visualized by a switch from red to green in those mesoblast cells in which swsn-1 was lost. The animals are healthy at 15C, but embryonic lethal and larval arrested at 23-25C. swsn-1(os22) causes mild overproliferation in the mesoblast lineage. The swsn-1 rescuing transgene is unable to rescue germline development of swsn-1(os22) mutants. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

maIs103[rnr::GFP unc-36(+)] X. The heDf1 deletion includes cdk-4. Heterozygotes produce 1/4 thin, sterile, uncoordinated animals that fail to undergo postembryonic somatic cell divisions. heDf1 mutants are of L1 size, smaller than cdk-4 mutants. lon-2 and unc-9 do not exactly balance heDf1, but unc-9 is pretty close. It should also be possible to follow the heterozygotes by looking at the GFP. Despite trying, unable to separate the maIs integration from heDf1 or the other cdk-4 alleles. By maintaining animals with GFP (visible especially in early animals and in eggs) you should be able to maintain heDf1. rnr::GFP is expressed during S-phase in heterozygous animals. rnr::GFP expression is not detected in heDf1 animals. maIs103 is tightly linked to heDf1.
