CULTURE OF CALLUS OF Hedera canariensis, WILLD
1THE ROCKEFELLER UNIVERSITY AND NEW YORK BOTANICAL GARDEN.
Summary
This study successfully maintained Hedera canariensis callus cultures from stems for three years through 29 passages. Callus was also established from petioles and cotyledons of the same plant species.
Area of Science:
- Plant biology
- Plant tissue culture
- Horticultural science
Background:
- Plant tissue culture is crucial for propagation and research.
- Hedera canariensis (Canary Island Ivy) is a widely cultivated ornamental plant.
- Establishing stable long-term callus cultures is essential for genetic studies and propagation.
Purpose of the Study:
- To establish and maintain long-term callus cultures of Hedera canariensis.
- To investigate the viability of callus derived from different plant tissues.
- To assess the stability of callus over successive passages.
Main Methods:
- Callus induction from stem explants of adult Hedera canariensis.
- Maintenance of callus on synthetic media through serial subculturing (29 passages).
- Callus culture initiation from petioles and cotyledons of Hedera canariensis.
Main Results:
- Successful long-term maintenance of Hedera canariensis stem callus for three years.
- Achieved 29 successive passages of stem callus cultures.
- Demonstrated successful callus culture initiation from petioles and cotyledons.
Conclusions:
- Hedera canariensis callus can be reliably maintained in vitro for extended periods.
- Callus cultures can be established from various vegetative tissues of Hedera canariensis.
- This methodology supports further research and potential propagation applications for Hedera canariensis.

The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.

02:57Plant Tissue Culture
Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.
01:21Cell Culture
Most vertebrate cells grow in vitro attached to a substrate as a monolayer, called adherent cultures. The flasks and plates used to grow cells are chemically treated to facilitate cell attachment. However, a few cell types, such as hematopoietic cells, can grow in a suspension. In contrast to adherent cultures, suspension cultures can grow in non-treated cultureware using magnetic stirrers or spinner flasks to agitate the culture media
01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
