In the past, acellular dermal matrices (ADMs) have been used in implant-based breast reconstruction. Various factors affect the clinical performance of ADMs since there is a lack of systematic characterization of ADM tissues. This study used BellaCell HD and compared it to two commercially available ADMs-AlloDerm Ready to Use (RTU) and DermACELL-under in vitro settings. Every ADM was characterized to examine compatibility through cell cytotoxicity, proliferation, and physical features like tensile strength, stiffness, and the suture tensile strength. The BellaCell HD displayed complete decellularization in comparison with the other two ADMs. Several fibroblasts grew in the BellaCell HD with no cytotoxicity. The proliferation level of fibroblasts in the BellaCell HD was higher, compared to the AlloDerm RTU and DermACELL, after 7 and 14 days. The BellaCell HD had a load value of 444.94 N, 22.44 tensile strength, and 118.41% elongation ratio, and they were higher than in the other two ADMs. There was no significant discrepancy in the findings of stiffness evaluation and suture retention strength test. The study had some limitations because there were many other more factors useful in ADM's testing. In the study, BellaCell HD showed complete decellularization, high biocompatibility, low cytotoxicity, high tensile strength, high elongation, and high suture retention strengths. These characteristics make BellaCell HD a suitable tissue for adequate and safe use in implant-based breast reconstruction in humans.
过去,脱细胞真皮基质(ADM)已被用于基于植入物的乳房重建。由于缺乏对ADM组织的系统表征,各种因素会影响ADM的临床性能。本研究使用了BellaCell HD,并在体外环境中将其与两种市售ADM——即用型AlloDerm(RTU)和DermACELL进行比较。对每种ADM进行表征,通过细胞毒性、增殖以及诸如拉伸强度、硬度和缝合线拉伸强度等物理特征来检查相容性。与其他两种ADM相比,BellaCell HD显示出完全脱细胞。在BellaCell HD中有几个成纤维细胞生长,且无细胞毒性。在7天和14天后,与AlloDerm RTU和DermACELL相比,BellaCell HD中成纤维细胞的增殖水平更高。BellaCell HD的负载值为444.94 N、拉伸强度为22.44、伸长率为118.41%,均高于其他两种ADM。在硬度评估和缝合线保留强度测试的结果中没有显著差异。该研究存在一些局限性,因为在ADM测试中有许多其他更有用的因素。在该研究中,BellaCell HD显示出完全脱细胞、高生物相容性、低细胞毒性、高拉伸强度、高伸长率和高缝合线保留强度。这些特性使BellaCell HD成为一种适合在人类基于植入物的乳房重建中充分且安全使用的组织。
