[EX Q]: Question: Does co-Transplantation of Skin-Derived Precursors and Collagen Sponge facilitate Diabetic Wound Healing by Promoting Local Vascular Regeneration?
Answer: Accelerated wound healing and enhanced local capillary regeneration could be observed 14 days after skin ablation from both SKPs and collagen sponge co-transplanted and collagen sponge only groups. Subsequent analyses further revealed superior pro-angiogenic effects from the SKP and collagen sponge co-delivered group, which are mainly attributable to in vivo transdifferentation and paracrine signalling of the SKPs.
[EX A]: yes

[EX Q]: Question: Is childhood maltreatment associated with depression but not with hypochondriasis in later life?
