“…This sequential, bilaterally-symmetric pattern has been also reported in cashmere goats (Ansari-Renani et al, 2011) and camels (Ansari-Renani, 2008, Ansari-Renani et al, 2010. Unlike natural shedding, cortisol injected Merino sheep, shedding of fiber starts from rump and belly areas extending to shoulders (Ansari-Renani et al, 2007).…”

Prion diseases which are a group of fatal neurodegenerative disorders affect both animals and humans. It is believed that the prions are infectious agents responsible for transmissible spongiform encephalopathies. The present study was performed to concentrate on the molecular and phylogenetic analysis of prion coding region in one-humped camels rearing in Iran. In order to assess the genetic relatedness of dromedary camels studied in Iran the nucleotide and deduced amino acid sequences of the prion region were compared with some corresponding sequences of earlier described mammalians. The nucleotide sequence comparison indicated that eight dromedary camels of Iran share approximately 100% similarity among themselves. Phylogenetic clustering in the prion coding region of all mammalians included in the analysis was distinctly divided into three lineages in which Iran-dromedary camel clustered with two species Sus scrofa and Equus asinus. Data analysis demonstrated that dromedary camel 2 from Germany contains one amino acid deletion in comparison to other camels. The codon (TGA) at position 564-566 has been deleted, leading to deletion of amino acid methionine at position 189. In comparison to other mammalians, all camels possessed an amino acid deletion at position 71 of amino acid sequence; the amino acid Gly has been deleted from this position. The existence of such genetic variations must be taken into consideration, if they are found to be related to the host resistance against the prion disease.

“…We inferred that the development of SF group was completed in the embryonic period, and the periodical change of SF was just the new SF replacing the old SF. About 25–30% SF of Raeini cashmere goat have been shown to be inactive in Winter and Spring (Ansari‐Renani et al, ), and 30–40% SF of camel have been shown to stop producing cashmere in March and April (Ansari‐Renani et al, ). We found that the density of SF in Hexi Cashmere goat did not synchronize with the activity of SF.…”

“…Hair follicle has been studied by researchers (Chase et al, ; Elaragno and Montagna, ; Mann, ) many years ago. New Zealand Cashmere goat, Mongolia Cashmere goat, Iranian Cashmere goat, Spanish Cashmere goat, and Gray goat have been studied by many researchers (Nixon et al, ; Li et al, ; Ansari‐Renani et al, ; Dong et al, ; Wang et al, ). However, there is no detailed research report on characteristics of SF in Hexi Cashmere goat.…”

This experiment was conducted to identify some aspects of secondary follicle (SF) characteristics of Hexi cashmere goats at five different growing stages in one year in order and discover the expression pattern of Hoxc13 in a SF cycling to provide morphological basis for studying the growth of cashmere. Ten cashmere goats of one-year old (5 males, 5 females) were included in this study. The density and activity of SF were observed and measured by making paraffin sections, the ultra-structural features of SF were studied under transmission electron microscopy (TEM) by making ultra-thin sections, and the expression of Hoxc13 was investigated through the immunohistochemistry method. The average diameter of SF had the smallest value in the anagen stage, and significant difference (P < 0.05) was found between the anagen stage and other stages. The density of SF increased gradually through the different growing stages, and significant difference was found between the anagen and procatagen stages (P < 0.05). With an increase in time (months), the percentage of SF activity increased, and significant difference in the percentage of SF activity was found between the telogen and anagen stages (P < 0.05). At the telogen stage, the layers of connective tissue sheath (CTS) of SF were unclear, hemidesmosomes between the outer root sheath (ORS) and basement membrane disappeared, and dead cells were found at the top of the SF. The rudiments of new SF were found in the proanagen stage, CTS was thickened, and the cells of ORS were stretched out like fingers. At the anagen stage, the structure of SF was integral, and the inner root sheath (IRS) consisted of three concentric layers (Helen, Huxley, and Cuticle layers). The cells of Huxley's layer degenerated gradually, and pseudopodia were formed on the cells of ORS in the procatagen stage. At the catagen stage, the ORS was separated from the IRS, and IRS disappeared. Huxley's layer was absent in the inactive SF while, the ORS was present in the active SF. Hoxc 13 was expressed in the epidermis and sebaceous gland o, ORS, IRS, hair shaft of SF in the skin. Hoxc13 was expressed weakly during procatagen, catagen, and telogen stage, while with an increase in proanagen and ana-
