Background

Development of bioprocesses for mammalian cells has to deal with different bioreactor types and scales. Bio-reactors might be intended for seed train and production, research, process development, validation or transfer purposes. During these activities, not only the problem of up- and downscaling might lead to failure of repro-ducibility, but also the use of different bioreactor geometries and operation conditions. In such cases, the criteria for bioreactor design and process transfer should be re-evaluated in order to avoid an erroneous transfer of cultivation parameters.

Concept

For selection of process conditions several questions can be asked:

  • Type and scale of the intended cultivation system

  • Which data are required (cell specific parameters, specific data for the cultivation system)?

  • Are appropriate data e.g. for cell growth, substrate uptake, medium composition available?

  • For which cultivation systems have these data been determined?

  • Are data on power input, mixing time, oxygen transfer etc. available?

  • Which methods can be used to determine or estimate the above mentioned parameters?

For selection and evaluation of suitable cultivation parameters a decision tree (Figure 1) has been formulated to provide a guideline for design of mammalian cell culture processes. References for process transfer strategies are given for the following cases:

  • Scale similar and power imput similar: [1–3]

  • Scale similar and power imput similar: [4–6]

  • Scale up and power imput similar: [7, 8]

  • Scale up and power imput similar: [4, 9, 10]
