Mesenchymal stem cell (MSC) therapies are emerging as a promising strategy to promote tissue repair, and may extend their utility to burn care. This comprehensive review of the extant literature, evaluated all in vivo studies, to elucidate the potential protective and therapeutic effect of MSCs in acute thermal skin burns. ⋯ MSC therapy show positive results, regarding improved burn wound healing and immunologic response. However, most findings are based on small animal studies. Randomized clinical trials are warranted to investigate the regenerative effects in human burns before translating the findings into clinical practice.

Determining the efficacy of anti-scar technologies can be difficult as qualitative, subjective assessments are often utilized instead of systematic, objective measures. Perceptions regarding the reliability of instruments for quantitative measurements along with their high cost and increased data collection time may discourage their use, leading to use of scar scales which are relatively quick and low-cost. To directly evaluate the reliability of instruments for quantitative measurements of scar properties, instruments and two qualitative scales were compared by assessing a variety of cutaneous scars. ⋯ Non-invasive instruments allow scar properties to be quantitatively assessed with high sensitivity and as a function of time and/or treatment without the need for biopsy collection. Overall, the reliability of scar assessments was significantly improved when quantitative instruments were utilized versus scar scales. Quantitative assessment of color and biomechanics were swift, requiring less than 90 s per measurement while assessments of texture and height required additional analysis time after collection. With proper training of clinical staff and well-defined protocols for measurement collection, reliable, quantitative assessments of scar properties can be collected with little disruption to the clinical workflow.
