Isolation and multilineage differentiation of bone marrow mesenchymal stem cells from abattoir-derived bovine fetuses
Background:
Mesenchymal stem cells (MSC) are multipotent progenitor cells localized in the stromal compartment of the bone marrow (BM). The potential of MSC for mesenchymal differentiation has been well documented in different animal models predominantly on rodents. However, information regarding bovine MSC (bMSC) is limited, and the differentiation potential of bMSC derived from fetal BM remains unknown. In the present study we sought to isolate bMSC from abattoir-derived fetal BM and to characterize the multipotent and differentiation potential under osteogenic, chondrogenic and adipogenic conditions by quantitative and qualitative analyses.
Results:
Plastic-adherent bMSC isolated from fetal BM maintained a fibroblast-like morphology under monolayer culture conditions. These cells expressed high levels of MSC surface markers (CD73, CD90, and CD105) and low levels of hematopoietic surface markers (CD34 and CD45). Culture of bMSC under osteogenic conditions during a 27-day period induced up-regulation of the osteocalcin (OC) gene expression and alkaline phosphatase (ALPL) activity, and promoted mineralization of the matrix. Increasing supplementation levels of ascorbic acid to culture media enhanced osteogenic differentiation of bMSC; whereas, reduction of FBS supplementation compromised osteogenesis. bMSC increased expression of cartilage-specific genes aggrecan (ACAN), collagen 2A1 (COL2A1) and SRY (sex-determining region Y) box 9 (SOX9) at Day 21 of chondrogenic differentiation. Treatment of bMSC with adipogenic factors increased levels of fatty acid-binding protein 2 (AP2) mRNA and accumulation of lipid vacuoles after 18 days of culture. NANOG mRNA levels in differentiating bMSC were not affected during adipogenic culture; however, osteogenic and chondrogenic conditions induced higher and lower levels, respectively.
Conclusions:
Our analyses revealed the potential multilineage differentiation of bMSC isolated from abattoir-derived fetal BM. NANOG mRNA pattern in differentiating bMSC varied according to differentiation culture conditions. The osteogenic differentiation of bMSC was affected by ascorbic acid and FBS concentrations in culture media. The simplicity of isolation and the differentiation potential suggest that bMSC from abattoir-derived fetal BM are appropriate candidate for investigating MSC biology and for eventual applications for regenerative therapy.
Insights
Mesenchymal stem cells (MSC) from fetal bovine bone marrow demonstrate multipotent differentiation potential. These cells are suitable for regenerative therapy research and applications.
Area of Science:
- Stem Cell Biology
- Regenerative Medicine
- Veterinary Science
Background:
- Mesenchymal stem cells (MSC) are multipotent progenitor cells found in bone marrow (BM).
- While rodent MSC differentiation is well-documented, bovine MSC (bMSC) data, especially from fetal BM, is limited.
- The multipotent and differentiation potential of fetal bMSC remains largely unknown.
Purpose of the Study:
- To isolate and characterize mesenchymal stem cells (bMSC) from abattoir-derived fetal bovine bone marrow.
- To evaluate the multipotent differentiation capacity of these bMSC under osteogenic, chondrogenic, and adipogenic conditions.
- To perform quantitative and qualitative analyses of bMSC differentiation potential.
Main Methods:
- Isolation of plastic-adherent bMSC from fetal bovine BM.
- Characterization of MSC surface markers (CD73, CD90, CD105, CD34, CD45).
- Induction of osteogenic, chondrogenic, and adipogenic differentiation with subsequent gene expression and activity analyses.
Main Results:
- Isolated bMSC exhibited fibroblast-like morphology and expressed characteristic MSC surface markers.
- Osteogenic differentiation showed increased osteocalcin gene expression, alkaline phosphatase activity, and matrix mineralization, influenced by ascorbic acid and FBS levels.
- Chondrogenic differentiation led to increased expression of cartilage-specific genes (ACAN, COL2A1, SOX9).
- Adipogenic differentiation resulted in increased AP2 mRNA levels and lipid vacuole accumulation.
- NANOG mRNA levels varied with differentiation type, being unaffected in adipogenesis but higher in osteogenesis and lower in chondrogenesis.
Conclusions:
- Fetal bovine bone marrow-derived MSC possess multilineage differentiation potential.
- NANOG mRNA expression patterns differ based on the specific differentiation pathway.
- Osteogenic differentiation is sensitive to ascorbic acid and FBS concentrations.
- These bMSC are suitable for MSC biology research and potential regenerative therapy applications.
