Advancing Professionalization of Biobank Business Operations: Performance and Utilization.

Biobanks are now in the spotlight as key enablers supporting preclinical, clinical, and environmental research. Awareness of their value has increased along with the need for these infrastructures to be sustained through business-focused practices. Following our 2017 pilot survey on biobank business planning, we initiated a more comprehensive 38-question multiple-language worldwide survey on biobank sustainability.

Advancing Professionalization of Biobank Business Operations: A Worldwide Survey.

Quality specimens from biobanks are key resources to support reproducible research. Sustaining biobanks requires robust management. We recently published a pilot survey that indicated that over half the participating biobanks had business plans in place and another third were working on business planning.

Considerations in establishing a post-mortem brain and tissue bank for the study of myalgic encephalomyelitis/chronic fatigue syndrome: a proposed protocol.

Background: Our aim, having previously investigated through a qualitative study involving extensive discussions with experts and patients the issues involved in establishing and maintaining a disease specific brain and tissue bank for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), was to develop a protocol for a UK ME/CFS repository of high quality human tissue from well characterised subjects with ME/CFS and controls suitable for a broad range of research applications. This would involve a specific donor program coupled with rapid tissue collection and processing, supplemented by comprehensive prospectively collected clinical, laboratory and self-assessment data from cases and controls.

Findings: We reviewed the operations of existing tissue banks from published literature and from their internal protocols and standard operating procedures (SOPs).

Adenovirus-based targeting in myoblasts is hampered by nonhomologous vector integration.

Chromosomal correction of dystrophin gene mutations is a most desirable therapeutic solution for Duchenne muscular dystrophy, as it allows production of the full-length dystrophin under the control of locus-specific promoters. Here we explored gene targeting in conditionally immortal mouse dystrophin-deficient myoblasts. We constructed an adenoviral vector for the correction of the mdx mutation, containing 6.

Lack of galectin-1 results in defects in myoblast fusion and muscle regeneration.

Galectin-1 has been implicated in the development of skeletal muscle, being maximally expressed at the time of myofiber formation. Furthermore, in the presence of exogenous galectin-1, mononuclear myoblasts show increased fusion in vitro. In the current study, we have used the galectin-1 null mouse to elucidate the role of galectin-1 in skeletal muscle development and regeneration.

The involvement of galectin-1 in skeletal muscle determination, differentiation and regeneration.

The dogma that a cell is rigidly committed to one tissue type has been heavily challenged over the past few years with numerous reports of transdifferentiation of cells between different lineages. Cells capable of entering lineages other than that of their tissue of origin have been identified in several diverse tissues. Recently we have focussed on a non-committed myogenic cell within the dermis that is capable, under certain conditions, of expressing muscle specific markers and even fusing to the terminally differentiated stage of muscle cell development.

Muscle stem cells.

Since its discovery four decades ago, the satellite cell of skeletal muscle has been implicated as the major source of myogenic cells involved in growth and repair of muscle fibres. This review not only looks at the role of the satellite cell in these processes but discusses how cells derived from other sources and tissues have recently been implicated in muscle formation and regeneration. Muscle itself also yields cells that contribute to other cell lineages although it is currently debated as to whether these cells originate within muscle or have migrated there from other tissues.

The effect of galectin-1 on the differentiation of fibroblasts and myoblasts in vitro.

Normal murine dermal fibroblasts implanted into the muscles of the mdx mouse, a model for Duchenne muscular dystrophy, not only participate in new myofibre formation but also direct the expression of the protein dystrophin which is deficient in these mice. We have reported that the lectin galectin-1 is implicated in the conversion of dermal fibroblasts to muscle. In the current work we confirm the presence of galectin-1 in the medium used for conversion.
