Superior cell culture device for more efficient biological production

描述(申请人提供)：对于生物技术核心的许多中小型细胞培养工作，传统的培养器皿，如烧瓶和滚筒，是唯一实用的设备。尽管它们易于使用和一次性使用，但它们的设计限制导致它们浪费劳动力、实验室空间、处置空间、生长因子、蛋白质回收材料和时间。本申请提出了一种远远优于传统培养器皿的新型细胞培养装置。这种新装置被称为“6X薄膜滚筒(6X MRB)”。它的外部形状为滚筒状，因此可以与标准的实验室设备接口。然而，它有一个独特的内部几何结构，使其能够在更少的空间内培养更多的细胞，浓缩细胞分泌的蛋白质，并减少生长因子的使用。预计每年将节省数百万美元。虽然设计理念在纸上看起来很强烈，但可行性需要通过生物性能测试来证明。因此，第一阶段的主要目标是确定当面对实际的生物学评估时，6X MRB概念是否会像假设的那样发挥作用。具体目标随之而来。目标1：按照我们的概念设计制作6X磁悬浮轴承测试装置。与传统的培养器皿相比，表面积将增加6倍，透析膜将允许细胞以高密度培养。交付：无菌6倍MRB测试设备，准备用于AIM 2测试。目的：通过对分泌EPO的BHK细胞、使用昂贵生长因子的间充质细胞和分泌病毒载体的PG13细胞进行生物学评价，确定6X MRB的可行性，以确定其相对于传统培养器皿减少细胞培养过程的成本的能力。交付内容：报告第二阶段是否需要担保。如果有保证，将提供一个设计数据库来指导第二阶段计划。 与公共卫生相关：对于生物技术核心的许多中小型细胞培养工作来说，烧瓶和滚筒等传统培养器皿是唯一实用的设备。尽管它们易于使用和一次性使用，但它们浪费了劳动力、实验室空间、处置空间、生长因子、蛋白质回收材料和时间。在没有更好的设备替代的情况下，在细胞培养上花费的大量资金中，有很大一部分被浪费了。一种新的细胞培养装置被提出，它可以克服这些问题，预计每年将允许数百万美元的资金从平凡的细胞培养活动转向更重要的研究方面。

DESCRIPTION (provided by applicant): For much of the small and mid-scale cell culture work at the core of biotechnology, traditional culture ware such as flasks and roller bottles are the only devices that are practical for use. Although they are easy to use and disposable, they have design limits that cause them to squander labor, laboratory space, disposal space, growth factors, protein recovery materials, and time. This application proposes a new cell culture device that is far superior to traditional culture ware. The new device is called the "6X Membrane Roller Bottle (6X MRB)." It has an outside shape that takes the shape of a roller bottle so that it can interface with standard lab equipment. However, it has a unique internal geometry that allows it to grow more cells in less space, concentrate cell secreted protein, and reduce the use of growth factors. Millions of dollars of savings are projected annually. While the design concept appears strong on paper, feasibility needs to be proven through biological performance testing. Thus, the primary goal of Phase 1 is to determine if the 6X MRB concept will perform as hypothesized when faced with actual biological evaluations. Specific aims follow. Aim 1: Fabricate 6X MRB test devices in accordance with our concept design. A six fold increase in surface area will be present relative to traditional culture ware and a dialysis membrane will allow cells to be cultured at high density. Deliverable: Sterile 6X MRB test devices ready for Aim 2 testing. Aim 2: Determine feasibility of the 6X MRB by conducting a biological assessments with BHK cells secreting EPO, mesenchymal cells using expensive growth factors, and PG13 cells secreting viral vectors to determine its capacity to cost reduce the cell culture process relative to traditional culture ware. Deliverable: Report whether or not Phase II is warranted. If warranted, a design data base will be available to guide the Phase II plan. PUBLIC HEALTH RELEVANCE: For much of the small and mid-scale cell culture work at the core of biotechnology, traditional culture ware such as flasks and roller bottles are the only devices that are practical for use. Although they are easy to use and disposable, they squander labor, laboratory space, disposal space, growth factors, protein recovery materials, and time. In the absence of a superior device alternative, a significant portion of the vast amount of money spent on cell culture is wasted. A new cell culture device is proposed that overcomes these problems and is expected to allow millions of dollars annually to be redirected from mundane cell culture activity to much more important aspects of research.
