Abstract: The present invention relates to a cosmetic composition having a cotton candy form. The cosmetic composition in a cotton candy form is prepared by freeze-drying an algin aqueous solution, and thus can be prepared through a simple process, has excellent moldability, and can stably contain, even at room temperature, a protein such as a cytokine, a peptide, and the like, which have particular storage requirements.

Abstract: The present invention relates to a composition for skin improvement containing at least one chemokine selected from the group consisting of B lymphocyte chemoattractant (BLC), also known as C-X-C motif ligand 13 (CXCL13), and thymus-expressed chemokine (TECK), also known as C-C motif ligand 25 (CCL25), as an active ingredient. Since the BLC (CXCL13) and TECK (CCL25) of the present invention increase the expression of proliferation marker Ki-67 and collagen IV, which are proteins concerning skin regeneration and skin elasticity, and exhibit excellent melanin-reducing and wound-healing effects and the ability to induce chemotaxis of keratinocytes, they can be applied in a cosmetic composition for skin improvement.

Abstract: There is provided a method for stably preserving cells and valuable materials included in the cells at room temperature by lyophilizing the cells. When the cells are lyophilized using a lyoprotectant, damage to the structure of the cells which may otherwise occur during a freezing process can be prevented, the lyophilized cells can be stored at room temperature, and the valuable material included in the cells may maintain the functions thereof at room temperature.

Abstract: There is provided a dressing for treating a wound. The dressing for healing a wound can be useful in maintaining a moisture environment at a wound site using a biocompatible polymer scaffold, and effectively promoting healing of a wound by various growth factors secreted by skin cells or stem cells attached to the biocompatible polymer scaffold as well.

Abstract: The present invention relates to an implantable composition for treating a damaged tissue and a method for inducing an in vivo migration of a cell for treatment to a damaged tissue region. The present invention treats the damaged tissue by inducing/promoting homing of a cell for tissue generation by implanting a biodegradable scaffold reacted with chemotactic factors (for example, IL-8 or MIP-3?) to a damaged location (for example, joint cartilage or skin). Thus, the composition of the present invention can not only be applied to the treatment of a damaged bone tissue, a joint cartilage, or a skin tissue more conveniently and efficiently compared to the conventional technology, but can also be used as a useful treatment supplement agent in cell treatment using allogeneic cell by enabling efficient utilization of cell resources for treatment, the cell resources which are high in scarcity.
