The first cloned camel in the world was Injaz, a female dromedary born on April 8, 2009, in Dubai, United Arab Emirates. Her name, Injaz, fittingly means "achievement" in Arabic, marking a significant milestone in the field of animal biotechnology.
The Birth of a Scientific Milestone
Injaz's birth was a groundbreaking event, showcasing the successful application of somatic cell nuclear transfer (SCNT) technology—the same technique used to create Dolly the sheep—in camels. This scientific triumph was achieved by researchers at the Camel Reproduction Centre in Dubai, placing the UAE at the forefront of cloning and genetic research for camel species.
How Injaz Was Cloned
The creation of Injaz involved an intricate process of reproductive cloning:
- Cell Source: Scientists used ovarian cells, specifically cumulus cells, which were obtained from the ovary of a slaughterhouse camel. These cells provided the genetic material for cloning.
- Enucleated Egg: An unfertilized egg cell was collected from a recipient camel, and its nucleus, containing the original genetic information, was carefully removed (enucleated).
- Cell Fusion: The ovarian cell (donor cell) was then fused with the enucleated egg cell using electrical pulses.
- Embryo Development: The reconstructed cell began to develop into an embryo, mimicking the early stages of natural fertilization.
- Gestation: The cloned embryo was implanted into the uterus of a surrogate mother camel, who carried the pregnancy to term, resulting in the birth of Injaz.
This method demonstrated the feasibility of cloning large livestock animals like camels, opening new avenues for genetic preservation and propagation.

The Significance of Camel Cloning
The success of Injaz underscored the potential of cloning technology for various applications in camel husbandry and conservation:
- Preservation of Elite Genetics: Cloning allows for the replication of camels with superior traits, such as high milk production, exceptional racing prowess, or resistance to specific diseases. This is particularly valuable in the camel industry, where top-performing animals command high prices and contribute significantly to breeding programs.
- Conservation: It offers a method to preserve the genetics of rare or endangered camel breeds, enhancing genetic diversity.
- Research Opportunities: Cloning provides researchers with genetically identical animals, which are invaluable for studying various aspects of camel biology, physiology, and disease resistance without genetic variability as a confounding factor.
Advancements in Camel Cloning Technology
Since the birth of Injaz, the Camel Reproduction Centre has continued to advance its cloning techniques. Initially, they utilized ovarian cells, as seen with Injaz. However, the Centre has since refined its approach:
- Expanded Cloning Efforts: More than two dozen camels have been successfully cloned since Injaz's pioneering birth.
- Shift to Skin Cells: The methodology has evolved, and the Centre now primarily uses skin cells for cloning. Skin cells are generally easier to obtain and culture, making the cloning process more efficient and less invasive. This continuous improvement highlights the ongoing commitment to enhancing biotechnology in the region.
Injaz's legacy continues to inspire further research and application of cloning technology, ensuring the propagation of desirable traits and contributing to the scientific understanding of these remarkable animals.
