Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Microcarriers (MCs), offering a large surface/volume ratio, are the most promising candidates for upscaling muscle cell culture.

Published Workflows
Objective: Design a scalable cultured meat bioprocess using microcarriers for skeletal muscle cell attachment and proliferation while minimizing downstream processing burdens.
Why it works: The review frames microcarriers as useful because they provide a large surface-to-volume ratio for muscle cell culture, and it compares process scenarios based on whether downstream carrier handling can be reduced or eliminated.

Stages
- 1.Temporary microcarrier expansion with later cell-carrier separation(functional_characterization)
This scenario supports cell expansion on microcarriers when the carrier is not intended to remain in the final product.
Selection: Use microcarriers as a temporary substrate for cell attachment and proliferation, followed by later separation from cells.
- 2.Temporary microcarrier expansion with in-process carrier degradation or dissolution(functional_characterization)
This scenario offers an alternative to physical separation by removing the carrier through degradation or dissolution during processing.
Selection: Use microcarriers as a temporary substrate for proliferation, then degrade or dissolve them during the bioprocess.
- 3.Edible microcarrier expansion with retention in final product(functional_characterization)
This scenario is favored because edible carriers can remain in the product and reduce downstream processing complexity.
Selection: Use microcarriers that are edible and can be embedded in the final product.

They must be integrated into a bioprocess for skeletal muscle cell culture and chosen or designed according to whether they will be removed, degraded, or retained in the final product.; design criteria depend on whether the carrier is temporary, degradable, or edible; must support skeletal muscle cell attachment and proliferation
The abstract does not claim that existing microcarriers are already optimized for muscle stem cells or complete meat production workflows; it explicitly notes that such specialized microcarriers had not yet been developed.; none have been specifically developed for muscle stem cells and meat production; some process scenarios require later separation, degradation, or dissolution steps

Ranked Claims
Among the three reviewed microcarrier bioprocess scenarios, the edible microcarrier scenario is described as the most promising for production.
Each scenario presents advantages and drawbacks, which are discussed in detail, nevertheless the third scenario appears to be the most promising one for a production process.
Existing microcarriers had not been specifically developed for muscle stem cells and meat production at the time of the review.
However, although many MCs have been developed for cell lines and stem cells typically used in the medical field, none have been specifically developed for muscle stem cells and meat production.
Using edible microcarriers can limit or eliminate dissociation, degradation, and separation steps and may improve organoleptic qualities when retained in the final product.
Indeed, using an edible material can limit or completely eliminate dissociation/degradation/separation steps and even promote organoleptic qualities when embedded in the final product.

Comparisons
Source-stated alternatives
The abstract contrasts three microcarrier-use scenarios rather than naming non-microcarrier alternatives. It emphasizes edible microcarriers as a more promising variant relative to temporary carriers that require extra downstream handling.
