Collplant通过新的基于胶原蛋白的Collink扩展3D生物打印产品。3d90 Bio-Ink

The votes for our annual awards ceremony are now in! Watch the2022 3D印刷行业奖重播以找出今年的赢家。

3D bioprinting specialist填料has added a new bio-ink to its material portfolio.

Known as ‘Collink.3D 90,’ CollPlant’s second recombinant human collagen (rhCollagen)-based material is said to feature enhanced mechanical properties that directly address the print requirements of hard and soft tissues. Compared to existing cell-culturing hydrogels, the ink is also said to facilitate faster cell migration, a benefit that could make it an ideal basis for developing regenerative medicines.

“We are very excited to continue to broaden our rhCollagen-based bio-ink offerings, providing our biopharma and academic customers the ability to print a variety of applications,” said CollPlant CEO, Yehiel Tal. “In addition to our product pipeline, bio-inks are an important and strategic platform that supports CollPlant’s efforts to pursue licensing and collaboration agreements with business partners, and we will continue to introduce new bio-inks and innovate in this area.”

“我们认为,由于其高生物功能,流变学特性和高纯度,我们的生物企业为现有商业生物墨水提供了有利的替代品。”

填料’s collagen-growing technology

Collplant的产品围绕着专有的基于植物的基因工程技术,该技术作为开发再生药物和医学审美治疗的一种手段。从本质上讲,该公司的方法看到它在遗传设计的烟草植物的叶子上生长胶原蛋白,后来被收获并加工成高度纯化的3D生物构材料。

胶原蛋白被视为创建再生药物的重要组成部分,目前是从动物和人尸体中提取的。然而,Collplant表示,这一过程充满了污染和过敏风险,同时对天然胶原蛋白进行严格的纯化可能会导致“不可逆转的修改”,从而“阻碍其生物功能”。

相比之下,据说该公司的无动物替代品与人体内部产生的替代方案相同,同时还具有增强的生物功能,高均匀性,并且在不良反应方面的风险更少。

在过去,Coldplant已与3D系统合作将其Rhcollagen Bio-Inks部署在组织生物打印应用中。United Therapeutics’ deal to license CollPlant’s technology两年前还看到它用来生产用于肾脏串行3D打印的材料,而今年早些时候,Collplant本身揭示了这一材料。3D生物打印乳房植入物it has developed are entering animal trials.

将Collink.3d 90带入市场

旨在建立在Coldplant的平台上Collink.3D 50Bio-Ink,Collink.3d 90以最大化3D生物打印应用中细胞活力的方式,使细胞迁移到凝胶矩阵中更快。根据该公司的说法,与许多商业水凝胶相比,细胞迁移至关重要,因此其新材料可以提供“无动物,无动物的人类细胞培养底物”。

Bio-INK基于已修饰的胶原蛋白,因此其原代胺,用于在体内执行代谢和生理功能的分子中,已变成了聚合物甲基丙烯酰胺。正是这种高水平的功能化导致凝胶凝固,并具有改善的机械性能。

Collplant补充说,鉴于其新扩展的碰撞链接的能力。3D范围能够产生高分辨率,可扩展的3D生物打印脚手架,以准确模仿人体组织的性质,它们也可以访问其他应用。

这些包括细胞培养,组织建模和药物发现以及组织工程甚至可植入的组织,该地区将其视为潜在的数十亿美元的机会。更广泛地,由于其与3D生物生物发电机和各种细胞类型的兼容性广泛,包括干细胞,多能干细胞,内皮细胞和上皮细胞,Collplant表示,其新的Bio-Ink为整个研究人员提供了“出色的生物学性能,一致性和安全性”行业。

Though implants, particularly organs, produced via 3D bioprinting still face numerous challenges before they can be deployed at any kind of scale, the technology continues to make advances at an experimental level.

More recently, clinicians at theClaudius Regaud Institute图卢兹大学医院通过治疗癌症将这项技术付诸实践患有3D生物打印鼻子的患者在他们的手臂上生长。将生物打印结构植入并植入了患者的前臂两个月后,被除去,血运重建并植入其脸上,作为突破手术的一部分。
