Electrical Callus and Callus Formation by Electret
Clinical Orthopaedics and Related Research, 1977The callus formed by passing an electric current through bone is called electrodynamic callus. The amount of electrical current determines the quality of the callus (osseous, cartilagenous, or fibrous). Callus forms first at the negative pole and grows toward the positive pole.

Callus Stimulation in Distraction Osteogenesis
Plastic and Reconstructive Surgery, 2002Distraction osteogenesis has been described as in vivo tissue engineering. The ability to stimulate this process for the repair of bony defects or lengthening of congenitally shortened facial structures is likely to significantly impact the field of craniofacial surgery.

Injury, 1997
The bony callus was investigated by staining with the PAS and von Gieson techniques. The callus appeared to be composed of two adjoining but distinct types of bone. The birefringence observed in the periosteum and callus cartilage revealed different sized collagen fibres, each oriented perpendicularly to the long axis of the diaphysis.

Callus formation and cucurbitacin B accumulation in Ecballium elaterium callus cultures
Fitoterapia, 2003Ecballium elaterium fruit juice is used for the treatment of sinusitis in Turkish folk medicine. The aim of this study was to increase the yield of cucurbitacin B, an anti-inflammatory compound previously isolated in various organs of E. elaterium, through tissue culture techniques.

Organogenesis in Callus Culture
2003Plant cells can be totipotent, i.e., each cell may be capable of developing into an entire plant when provided with the correct environmental stimuli. Research during the last 30 yr has demonstrated that successful organogenesis in callus cultures can be achieved by the correct choice of medium components, selection of a suitable inoculum, and control ...

Callus Cultures of Arabidopsis
Current Protocols in Microbiology, 2006AbstractProtoplasts are plant cells lacking cell walls. They can be generated from stationary callus cultures derived from Arabidopsis thaliana seedlings. After treatment of the callus with cellulase and pectinase, protoplasts are inoculated with viral RNAs using polyethylene glycol.

[Optimization of noni callus induction and establishment of callus suspension system].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2019The aim of the study was to obtain the secondary metabolites in the stem segment of noni and to establish genetic transformation system. The stem segments (no axillary buds) of noni were used as explants to induce the callus, and then to establish the cell suspension system. The factors affecting callus induction and cell suspension were studied.

Breakdown of phosphatidylinositol in soybean callus [PDF]
Planta, 1986 We have investigated the breakdown of membrane-bound phosphatidylinositol (PI) in homogenates of soybean (Glycine max) callus. The breakdown of PI was stimulated by the detergent deoxycholate. At pH 7.0 and 1·gl(-1) of deoxycholate the loss of PI was rapid and extensive: more than 80% was broken down within 10 min.

The effect of micromovement on callus formation
Journal of Orthopaedic Science, 2001Micromovement at fracture sites is known to promote callus formation and bridging of the bony fragments. The present study was conducted to identify the suitable amount of micromovement, and to analyze the location and timing of callus proliferation. A standardized transverse osteotomy, in the right metatarsus of 32 sheep, was used as a fracture model.

1973
Publisher Summary This chapter discusses the culturing of aspen callus. It discusses that firm white callus from aspen trees has been initiated and maintained in an actively growing condition since 1961 at The Institute of Paper Chemistry. Seven species of Populus have been cultured, as well as numerous hybrids and polyploids.
