Endogenous Thymosin β4 Expression in Sacrococcygeal Pilonidal Sinus Disease: A Retrospective, Immunohistochemical Analysis of Excisional Skin Biopsy Samples.

Endogenous Thymosin β4 Expression in Sacrococcygeal Pilonidal Sinus Disease: A Retrospective, Immunohistochemical Analysis of Excisional Skin Biopsy Samples. Ostomy Wound Manage. 2017 Apr;63(4):30-40 Authors: Sahin S Abstract Thymosin beta 4 (Tβ4) is a peptide that has been shown in dermal, corneal, and cardiac preclinical injury models to potentially affect tissue protection, regeneration, and repair. Sacrococcygeal pilonidal sinus disease (SPSD) is a chronic inflammatory disorder associated with a high incidence of recurrence, chronic fistulation, and a challenging postoperative surgical wound healing process. Retrospectively, an immunohistochemical analysis was conducted to evaluate endogenous Tβ4 expression in excisional skin biopsies from patients with SPSD. Patient demographics (age, gender) and surgical procedure data were obtained from their electronic medical records. Two (2) samples were cut from each specimen and prepared for histopathological assessment: 1 from the inflamed sinus tracts containing hair and granulation tissue (chronic wound group) and 1 from the normal tissue at least 1 cm away from the sinus tract (control group). Tβ4 expression was evaluated in the epidermal, dermal/subcutaneous collagen, and vascular structures of the samples from the sinus tract and healthy tissue. Inflamed sinus tract tissue and noninflamed normal tissue adjacent to the sinus tract were sampled from each specimen to confirm the di...
