Gene symbol and name  Tcf21 (transcription factor 21), Po, ep
Strain of origin

C57BL/6

Chromosome  10

Application

  • Function research of genes
  • This Tcf21iCreERT2 model is an efficient tool to study various gene functions when crossed with mice with different loxP site-flanked genes of interest, especially in studies of Transcription factor 21 expressed during mouse embryogenesis specifically in mesodermally-derived cells that surround the epithelium of the developing gastrointestinal, genitourinary, and respiratory systems, and may be useful for studying mouse embryonic development. 

Expression


Expressed gene

Cre, cre recombinase, bacteriophage P1


Site of expression

Bladder adult, Lung adult, mouse embryos in mesenchymal cells 


Gene editing strategy


from clipboard


A iCreERT2-WPRE-pA sequence cassette was inserted downstream 5’UTR of the Tcf21 gene. This strain was maintained on a C57BL/6 genetic background.

Figure 2. Blocking SEV secretion from ECs delays AML progression. (A) The experimental design. (B–F) Survival curves of AML recipients with different genotypes. Cdh5-Cre;Vps33bfl/fl (B), Lepr-Cre;Vps33bfl/fl (C), Osx-CreER;Vps33bfl/fl (D), Pf4-Cre;Vps33bfl/fl (E), and Tcf21-CreER;Vps33bfl/fl (F) are shown (n = 5–8; **P < 0.01, ***P < 0.001, log-rank test). Experiments were conducted 3 times for validation.

They used 7 cell type–specific mouse Cre lines to conditionally knock out Vps33b in Cdh5+ or Tie2+ endothelial cells (ECs), Lepr+ BM perivascular cells, Osx+ osteoprogenitor cells, Pf4+ megakaryocytes, and Tcf21+ spleen stromal cells.
