Project description:Mouse embryos at the E10.5 stage display the ability to regenerate their limb buds, however this is quickly lost during embryogenesis . In the present study, we identified the E12.5 stage as the stage at which regeneration is lost. To deepen our understanding of the transcriptomic programs established during regeneration we generated microarray data from post-amputation tissues at E10.5 and E12.5 stages with a particular focus on early response to amputation observed at 1 and 3hpa. We believe this dataset will help understand how regeneration works in mammals as well as the key differences in a non-regenerative context.
Project description:m6A regulates virtually every step in RNA metabolism. However, its toles in limb development remains largely unknown. To understand the roles, we created a limb bud-specific conditional knockout (cKO) mice and control heterozygous (cHet) mice of the Mettl14 gene, which encodes an essential subunit in the m6A methyltransferase complex METTL3/METTL14. We harvested limb buds from the mice on E12.5 and applied the proteins to quantitative mass spectrometry to understand how the depletion of Mettl14 affected the proteomes.
Project description:We established the differentiation method of a limb bud organoid from mouse embryonic stem cells (mESCs) using SFEBq. mESCs-derived limb bud organoid selectively differentiate into forelimb or hindlimb by adjusting the retinoic acids activity. To evaluate a correlation of gene expression between limb bud organoid and embryonic tissues (limb bud, branchial arch, cardiac, and tail bud), we performed comparative transcriptome analysis using RNA-seq.
Project description:Analysis of mouse limb bud (E10.5) lacking the Bhlha9 gene. Bhlha9 knockout mouse shows syndactyly and poliosis in the limb. This microarray results provides insight into the molecular mechanisms underlying Bhlha9 function in the limb development DNA microarray analysis was performed using Affymetrix mouse genome 430 2.0 array. RNA samples were obtained from the whole limb bud of the E10.5 wild-type and Bhlha9 knockout embryos described above. Total RNA (200 ng) was reverse-transcribed and biotinylated using the GeneChip 3â² IVT Express Kit (Affymetrix). The microarray data were summarized using the MAS 5.0 method.

Project description:Comparing gene expression of cells from the E10.5 limb bud ZPA and the rest of the E10.5 limb bud from Shhgfpcre heterozygotes separated by FACS. Experiment Overall Design: 8 samples, 4 ZPA and 4 rest of the limb
Project description:Shh signal mediated by Gli family of transcription factors regulates digit growth and patterning in early limb development. Shh expression in the posterior margin of the limb bud defines the zone of polarizing activity. However, much less is know about downstream targets that mediate Shh signal functions. In this dataset, we include the expression data obtained from dissected anterior and posterior halves of mouse limb bud respectively. These data are used to obtain 889 transcripts that were upregulated 1.3 fold or more in the posterior limb bud, and 1189 transcripts that were enriched in the anterior limb bud at 1.3 fold or more.

Two samples were analyzed. We generate pairwise comparisons between anterior and posterior limb tissues. Genes with a fold-change ≥1.3 were selected.
