Double-layer dissolving microneedles for delivery of mesenchymal stem cell Secretome: Formulation, characterisation and skin irritation study
Regenerative therapy based on stem cells have been developed, focusing on either stem cell or secretome delivery. Most marketed cellular and gene therapy products are available as injectable dosage forms, leading to several limitations requiring alternative routes, such as the intradermal route. Microneedles, capable of penetrating the stratum corneum barrier, offer a potential alternative for intradermal delivery. This present study aimed to develop double-layer dissolving microneedles (DMN) for the delivery of freeze-dried mesenchymal stem cell secretome. DMNs were fabricated using a two-step casting method and composed of two polymer combinations: poly(vinyl pyrrolidone) (PVP) with poly(vinyl alcohol) (PVA) or PVP with sodium hyaluronate (SH). The manufactured DMNs underwent assessments for morphology, mechanical strength, in skin dissolution, protein content, in vitro permeation, in vivo skin irritation, and physical stability. Based on evaluations of morphology and mechanical strength, two formulas (F5 and F12) met acceptance criteria. Evaluation of protein content revealed that F12 (PVP-SH combination) had a higher protein content than F5 (PVP-PVA combination), 99.02 ± 3.24 μg and 78.36 ± 3.75 μg respectively. In vitro permeation studies showed that F5 delivered secretome protein by 100.84 ± 0.88%, while F12 delivered 99.63 ± 9.21% in 24 h. After four days of observation on Sprague-Dawley rat’s skin, no signs of irritation, such as oedema and redness, was observed after applying both formulations. The safety of using PVP-PVA and PVP-SH combinations as excipients for DMN secretome delivery has been confirmed, promising significant advancements in biotherapeutic development in the future.
