Cell Specific Gene Expression

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Background:

Mesenchymal stem cells (MSCs) are crucial for cultivated fat production but are highly heterogeneous.
Identifying specific pre-adipocyte populations within MSCs is key to optimizing fat yield.
Current MSC applications are limited by the low proportion of true adipogenic progenitor cells.

Purpose of the Study:

To elucidate the molecular characteristics of porcine pre-adipocytes with high (H) versus low (L) adipogenic potential.
To generate and analyze bulk RNA sequencing data from clonal porcine MSC populations.
To identify differentially expressed genes associated with adipogenic capacity in farm animals.

Main Methods:

Single-cell fluorescence-activated cell sorting (FACS) of porcine MSCs.
Chemically-induced differentiation and Oil Red O staining to assess adipogenic capacity.
Bulk RNA sequencing and bioinformatics analysis (PCA, differential gene expression).

Main Results:

Bulk RNA sequencing data from H and L clonal populations were generated and analyzed.
PCA plots indicated partial overlap in gene expression profiles between H and L populations.
Differential expression analysis identified 30 upregulated and 67 downregulated transcripts in H clones, including known adipogenic genes like PPARG and FABP4.

Conclusions:

The study provides valuable datasets on porcine pre-adipocyte molecular signatures.
These findings can aid in the selective enrichment of MSCs for efficient cultivated fat production.
This research contributes to improving the sustainability of both traditional and cultivated meat production through better understanding of livestock cell biology.
