To investigate the acute and subacute effects of high nicotine concentrations on human mesenchymal stromal cells (MSCs) and their implications for users of smokeless tobacco products, particularly focusing on the differences in cellular responses over time.
Key Findings:
Nicotine exposure at varying concentrations significantly affects MSC proliferation and differentiation, with implications for users of smokeless tobacco products.
High concentrations of nicotine induce apoptosis and necrosis in MSCs, raising concerns about cellular health.
CSE exposure also leads to significant cell death and metabolic impairment, highlighting the risks associated with tobacco use.
Interpretation:
The study highlights the detrimental effects of nicotine and cigarette smoke on MSCs, which may contribute to oral and systemic health issues in users of smokeless tobacco products, emphasizing the need for awareness and preventive measures.
Limitations:
The study is limited to in vitro conditions and may not fully replicate in vivo responses, which could affect the applicability of the findings.
The small sample size of MSC donors (six) may limit the generalizability of the findings to broader populations.
Conclusion:
The findings underscore the need for further research on the long-term effects of nicotine and smokeless tobacco products on mesenchymal cell function and oral health, particularly focusing on the mechanisms of action and potential therapeutic interventions.
