MatTek公司是麻省理工学院两个化学工程教授于1985成立的科技公司。1991年,该公司利用其核心的聚合物表面改性技术进入新兴的组织工程领域,目前已成长为的组织工程技术公司,致力于生产创新性的3D重构人体组织模型,该模型相较于传统2D细胞模型具有更可靠的实验结果。其生产的重构皮肤,眼部和呼吸道组织模型已广泛应用于化妆品,化工,医药和家用产品等行业的毒理学监控(OECD,欧盟的指导方针)及毒理学研究。


MatTek公司的基于人体细胞的3D皮肤模型EpiDerm1993年研发上市,立即获得巨大的成功。从此MatTek通过以下方式彻底改变了基于人体细胞的体外模型市场:(1)低成本(降低50-80%的成本);(2)通过发表质量控制标准(同时具备阳性和阴性对照)以确保可为行业及监管机构接受的高可重复性水平;(3)优化研究人员的实验结果。通过创造性使用非动物的体外测试,融合降低(直接/间接)成本的强大协同效应及显著提高的产品质量,MatTek极大的降低产品成本、提高实验室效率及高质量的高可重复性产品,减少实验动物的使用,具有无可超越的长期组织可重复性;3-D仿真结构;高度分化的组织模型;代谢和分裂活性;源于正常的人体细胞;培养、操作简便;无血清培养;可定量的客观检测;物美价廉的优点。因而使得MatTek人细胞来源的体外组织模型被包括美国、加拿大、欧洲、日本和东亚的众多跨国公司与研究机构采用。


目前MatTek公司的产品主要包括EpiDerm(皮肤模型)、MelanoDerm(黑色素模型)、EpiOcular(眼周表皮模型)、EpiAirway呼吸道上皮模型)、EpiDermFT (全厚的皮肤模型EpiVaginal(阴道上皮模型)、EpiOral(口腔上皮模型)、 EpiGingivalTM(牙龈上皮模型)、Psoriasis tissue(牛皮癣组织模型)及树突细胞。
